Born in 2000.
Reborn in neon.
Blocktrix was a cult classic — a fast, mean, multiplayer riff on falling blocks where clearing lines was just ammunition. It's back, rewritten in a modern engine with buttery input, online and local play, CPU opponents, and a full arsenal of specials.

News & updates
What's changed lately — grab the newest build from the download section, or read the full changelog.
-
Journey mode, a channel browser, and a redesigned profile card
- Journey — a new solo mode. Survive each built-in map without topping out for a rising time (10s, then 20s, 30s…). Clear the timer and a cinematic transition sweeps you to the next map, a new theme and a new soundtrack. Score = total seconds survived.
- Channel browser. A new Browse channels picker: paginated cards showing each channel's art, live population, who's in it right now, and your own play history there — tap to join.
- Clean-garbage channels. New #CleanGarbage and #FastCleanGarbage rooms where incoming garbage stacks its hole into a single diggable column.
- Redesigned profile card. Profile and Stats tabs with a radar stat-map, a live This Game tab (level, pieces, PPM, lines sent/received), and session stats even for unregistered players — openable in-game from a player's title bar.
- New cosmetics. A Monotone garbage option, a Crystal Stars hard-drop trail, the Prism Blocks attack effect, and a row-by-row collapse on multi-line clears.
- Fixes & polish. Crisper Founder pill (no stray crest after a channel hop), away-status no longer leaks when you spectate, specials appear the instant lines clear, smarter bots, and a leaner engine. Full changelog →
-
Six new themes, endgame stats, and a big feel & latency pass
- Theme Pack 2 — Heroes, Glam & Cartoon. Three bold new premium themes in one code: Heroes (comic-book action), Glam (80s hair-metal stage) and Cartoon (Saturday-morning pop), each with its own backdrop, ambient effect & soundtrack. Get the pack →
- Three more themes, free or earnable. Abyss (deep-sea) is free for everyone; Cipher (code vortex) unlocks when you clear 2,000 solo lines; and Prism is earned by sharing Blocktrix with a friend. Plus a new Rounded block skin and theme-matched sound effects.
- End-of-game stats & better spectating. Regular games now finish with a per-player results table (lines, tetrises, specials); spectators see every board in an equal grid; and topping out — in a game or a raid — now drops you into that grid to watch the rest instead of a static death screen.
- Snappier to play. A latency pass — first move on key-down, buffered hard-drop, agile input flushing, retuned desktop audio/vsync — plus faster, cleaner held repeat-attacks.
- Raid & replay. The Overseer now taunts the squad when a raid ends and spectators get the raid FX/HUD; replays collapse fallen boards, exit to the menu cleanly, and stop the music when they end.
- Fixes & polish. Fixed opponent-field desync with 2.0 specials/Concrete, clearer connect errors (a taken nickname now tells you so), a double drop sound in TetriFast, no phantom "new message" after joining a room, crisper text and leaner networking. Full changelog →
-
New effects, custom Ghost colour & smoother online play
- New in-game effects. Soft-body jelly blocks (on by default), a reactive grid that lights up under your piece, a materialize-in spawn, an idle-HOLD glint, and rolling odometer HUD numbers — all toggleable in Settings → A/V.
- Custom Ghost colour, free for everyone. Tint the ghost piece any colour, or have it borrow the piece's own colour, right under the Ghost-piece toggle.
- Truer rotation feel. Hold a rotate key to keep spinning, and a piece pulled back from HOLD returns to the same column and orientation — like the classic client.
- Discord Rich Presence (desktop). Show your Blocktrix status — in a match, the lobby, spectating, and the public server you're on — in Discord.
- Smoother mid-game joins. Every board appears at once when you join a running game, your own death screen shows immediately, and you spectate the rest; topping out online keeps you watching instead of bouncing you to a game-over screen.
- New ways to play. A One in the Chamber channel, specials-only #Sniper / #FastSniper channels, and switchable audio-visualiser styles — plus crisper desktop text and a batch of raid and online-play fixes. Full changelog →
-
RAID MODE — co-op boss battles
RAID MODE — team up and take down the Overseer in #Overclock & #Overdrive. - New: Raid Mode. Team up (2+ players) in #Overclock or #Overdrive and take down the Overseer. Your line clears and offensive specials auto-aim the boss — break its 3 shields, then crack its hull. It fights back, speeds up as it weakens, enrages when exposed, and unleashes squad-wide barrages. Top out and you spectate until the squad wins or wipes. Full raid rules & scoring →
- Score & play solo. Clear a raid and each member earns winlist points for the damage they dealt (the killshot earns a bonus). Nobody online? As the room host, /raidfill adds AI teammates so you can raid alone — and /raidrules explains everything.
- Ready-up auto-start. An optional ready-check kicks off the match the moment everyone's set, so nobody waits on the host.
- New theme & achievements. A 12th theme — Ukiyo-e (indigo, sakura, koto) — unlocked by a new 7-day solo Ritual streak, plus raid-clear and win-streak achievements.
- Replay scrubber. The web replay player now has a seekable timeline — click or drag to jump anywhere — and raids replay with the boss tower and result.
- Faster, steadier online. A big performance pass for busy rooms, a fix for a partyline/room-change hitch on native clients, and per-device layout tuning so phones and tablets both fit.
-
Name styles, live cosmetic previews & a fix pass
Custom death fields — design the board that fills in when you top out. - Custom death fields (Blocktrix Plus). Design the board that fills the screen when you top out — paint your own or pick a preset (heart, invader, skull and more). Save several and share them as codes.
- Subscriber name styles & new achievements. Blocktrix Plus adds animated partyline name styles — shimmer, duo-chrome, neon glow and wave — plus five more achievements to earn.
- Live cosmetic previews. Every cosmetic in Settings now has an ⓘ button that plays a live preview — see a block skin, attack arc, line-clear effect or spawn style in motion (and page through the options) before you choose.
- Smoother play. The periodic in-game frame dips are gone (the settled board is cached) and the brief freeze at game over is fixed.
- Multiplayer fixes. The Switch special no longer hands you a mangled, half-empty board; your death field renders solid to everyone instead of full of holes; #SnS deals sticks and squares (not T-pieces); and leftover specials can't fire from the lobby.
- Cleaner switching & polish. Each channel now opens on its own MOTD with a jump-to-latest button, the win flourish actually plays, the menu pieces gained parallax depth, and mobile sizing is tidier.
- Classic theme fixes. The 2.0 specials now render right in the original Classic block art, and the Classic soundtrack loops seamlessly (in-game music also stops when you spectate).
- macOS download fixed. The packaged macOS app now launches correctly — an earlier build extracted without its executable bit and macOS refused it with "can't be opened." If you hit that, just re-download.
-
#Sprint, sudden death & a big authenticity pass
- New: #Sprint. A solo race to clear 40 lines against the clock — three runs a day, fastest time wins. It has its own monthly leaderboard, a Champions board on the home page, and per-run history on your profile.
- Sudden death. Long matches can't run forever now — any full-specials room that passes five minutes starts raining a garbage line on everyone until someone tops out.
- Flash the taskbar (desktop). When Blocktrix is in the background, incoming chat, private messages and in-game messages — plus players joining, leaving or switching channels — flash the taskbar button. Toggle it in Settings.
- Truer to the original. Classic line-clear garbage leaves exactly one hole again (the Add Line special stays random), and a piece shoved by an attack now settles where it's pushed — just like the 2000-era client.
- Spectating & watch fixes. Join a live game and every board shows correctly (no phantom extra field, no doubled "player 1"), the attack log clears,
/whoand other commands work from the watcher seat, and the channel list no longer highlights a room you've left. - Defaults & polish. CRT filter now off by default (flashing specials on); the drop sound no longer fires when you hold the drop key before a piece spawns; d-pad menus scroll to off-screen items without shifting sideways; a gentler solo Pure Survival ramp; the channel-list scrollbar fades when idle.
-
Cleaner join-in-progress & easier in-game chat
- Join a live game and it just looks right. Every opponent's full board shows the instant you join, with no stale "WINNER" tag and no dark, dead-looking board left over from the previous round.
- Chat without opening the panel. In-game messages pop as a toast at the top of the screen, and you can reply on the spot — press T (or the CHAT button on phones & controllers) for a one-line box that sends and vanishes.
- Spectators have names now. Chatting from a watcher seat shows your nick instead of "Server".
- Emoji in chat. Emoji shortcodes now render as real glyphs across the partyline and in-game chat — and the #AllAround score announcement no longer shows a stray "?".
- Controller & d-pad navigation. The main menu takes focus the moment the app opens, moving down now auto-scrolls to reach controls further down a list, the Achievements grid is fully navigable with a clear highlight, and dialogs open scrolled to the top instead of the bottom.
- #AllAround history restored. Every daily run records to your web profile again — not just your single best.
- New on the site. Deep-dive guides for the specials, the client & commands, all 12 themes and every game mode.
-
Solo achievements, LAN play, per-special sound & a stability pass
- Achievements & badges. Registered players now earn achievements in ranked play — shown as badges on your web profile with an in-game toast when you unlock one — and solo games vs the CPU earn their own set, browsable from the new Achievements tile in Play Solo. Unlocks and #AllAround progress broadcast to the room.
- Play on your LAN. Host a game and players nearby see it automatically — no IP typing. The client and built-in server now find each other on a local network.
- A sound for every special, plus glow. Each special has its own distinct sound effect, and a new setting makes special blocks glow so they stand out.
- Smoother spectating. Join a game in progress and see every field instantly, run
/commandswhile watching, and take an open seat mid‑game — you only watch when the room's full. - Big stability pass. Far fewer disconnects during busy matches, no more getting dropped the instant a game starts, fairer bots (no unreachable placements, difficulty sticks), plus a searchable bug tracker, profile search autocomplete and fewer download captchas.
-
Spectate, replays, Quick Play & player profiles
- Spectate & replays. Watch any game in progress without taking a seat — then grab a seat the moment one opens. And every online match is now auto‑saved, so you can replay it later with pause, restart and speed controls.
- Jump straight in. Quick Play drops you into the busiest room in one tap, and a friendlier first run offers "Play now vs CPU" with a difficulty you choose (easy → insane).
- Player profiles. Every registered player now has a profile page — lifetime stats (win rate, PPM, 4Tris%, downstack) plus your #AllAround history. Open one from any leaderboard name, the in-game profile card, or the new
/profilecommand. - A livelier lobby. See who's online and where at a glance — channel player counts update live, and in the modern layout you can drag the channel rail and roster columns to any width, remembered between sessions.
- Fixes & polish. Teammates no longer garbage each other on line clears, Quick Join keeps your Founder badge & flair, bot channels show the CPU's difficulty when you join, an in-app banner flags new versions, and disconnecting clears the old server's lists cleanly.
-
Lobby overhaul, Revenge & the Deck
- Redesigned lobby & chat. Choose your partyline layout — a modern grouped view with a channel rail, a thumb-friendly mobile layout, or classic tabs. Channel names in chat and MOTDs are now clickable, a glow marks the channel you're in, and a live typing indicator animates.
- Revenge & smarter targeting. Your last attacker gets highlighted and a single (rebindable) Revenge key fires straight back at them. Prefer aiming by hand? Flip on relative targeting in Settings so "1" always means you.
- Steam Deck: full support. A built-in on-screen keyboard, a Gaming-Mode performance fix, and no more phantom d-pad inputs that caused double moves.
- Fixes & polish. Mutation no longer stacks on itself, the attack log numbers each game from 1, #AllAround counts you in with a 3‑2‑1 and returns you to the lobby cleanly, classic-theme dialogs are readable, and smooth sideways slide is on by default.
-
Steam Deck, Linux & macOS
- Steam Deck & Linux controller fixes. The D-pad now moves one cell per press, pressing Up hard-drops without an extra rotation, and menus & drop-down lists navigate correctly.
- Tutorial sizing. The how-to-play guide now fills the whole window on Linux and the Steam Deck.
- Online server browser. More reliable — it retries a slow first connection instead of giving up.
- macOS is still unofficial. The macOS build is an unofficial community extra — now ad-hoc signed, so it runs on both Apple Silicon and Intel Macs. It isn't notarised by Apple, so on first launch, right-click the app ▸ Open to get past Gatekeeper. See the download page for details. Windows, Linux & Android are the officially supported builds.

Blocktrix 2.0 Beta
Modern partyline chat, private messages, four new 2.0 specials (Blackout, Concrete, Shield, Mutation), mobile-only channels, and lots of polish across the board.
Weaponize
the chaos
Every line you clear loads your inventory. Fire add-lines, nukes, bombs, quakes, gravity and field-switches at any rival on the board — then watch the garbage rise on their side, not yours.
- Real-time online matches
- Aim & attack any opponent
- 12 classic specials + 4 all-new for 2.0
- Outlast the room to win
New for 2.0
A whole new arsenal
Beyond the twelve classics, Blocktrix 2.0 servers unlock four brand-new attacks — cross-compatible so old and new clients can share a room.
Blackout
Rolling fog swallows the target's field for a few seconds — stack blind, or wait it out.
Concrete
Wedges an indestructible steel row into their stack. No clear removes it — only a nuke.
Shield
Raise a bubble that absorbs the next hostile special — including add-lines. Time it well.
Mutation
The target's next few pieces spawn as five-block mutants — an extra cell glued on to wreck their plans.
Two worlds, one game
Play it loud in Synthwave neon, or drop into the faithful Classic skin — original block art, Windows-XP chrome and all. Seven free themes ship in the box — Synthwave, Classic, Cosmos, Emerald, Crimson, Retro & Rainy Day — each with its own palette, backdrop, ambient effect and soundtrack. Four more (Founder + the Theme Pack) unlock below — plus a twelfth, the woodblock Ukiyo-e theme, earned in-game.
Play anywhere
One game, three platforms — Windows, Linux and Android — with full gamepad and touch support, plus an Assist mode that suggests the best drop with a tap.
Solo & bots
No server? Battle CPU opponents, or chase records in Marathon, Sprint, Survival and more.
200+ original maps
Hand-built community maps from the original era, each with its own block mix and sudden death.
New — the lobby's alive
Chat like it's 2026
The old partyline got a full rebuild. Grouped messages, colour-coded names, avatars, reactions, @mentions and one-to-one DMs — all still byte-compatible with original clients, so newcomers and veterans share the same room.
Modern partyline
A clean, Discord-style chat — grouped bursts, timestamps, avatars, colour names, clickable links and markdown-lite formatting. Classic plain-text mode is one tap away.
Private messages
DM any player in docked tabs over the lobby — with "typing…" indicators, quote-replies, reactions and a rich profile card on tap.
Reactions & emoji
React to any message with a tap, drop emoji by shortcode, run quick /polls and dice rolls — and legacy clients still read every word.
Subscriber stickers
A die-cut sticker set — cute characters and word art — for Blocktrix Plus members. Drop them in the partyline or a DM.
In the wild
