EST. 2000 — REBORN 2026

Blocktrix

The block battle is back.

The cult multiplayer block game from 2000 — rebuilt in a modern engine with silky-smooth play. Clear lines, weaponize specials, and bury your rivals in garbage. Online, offline, everywhere.

  • Windows
  • Linux
  • Android
  • Controller-ready

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.

Same ruthless game. New era. Visit the classic archive →

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
A live Blocktrix match: a neon playfield filling with coloured blocks, five rival fields stacking up, and a glowing synthwave sun behind the boards.

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.

A live match with the Blackout special active — rolling fog blankets a player's field with a small countdown timer, while rivals stack up alongside.
Blackout in action — the target stacks blind until the fog lifts.

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.

Blocktrix in the Synthwave theme — glowing neon blocks and a retro sun.
Synthwave — outrun neon, the default era
Blocktrix in the Classic theme — the original block art on a grey Windows-XP style window.
Classic — the original, faithfully restored

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.

The Founder theme — molten gold on cracked obsidian.

Drop in. Beta

Free, no account, no nonsense. Grab a build and join a server — or host your own.

The macOS build is an unofficial, unsupported community extra — ad-hoc signed (it runs on Apple Silicon and Intel) but not notarised by Apple, so macOS will still ask you to confirm on first launch: right-click the app ▸ Open. The bundled read-me walks you through it. Windows, Linux & Android are the officially supported builds.
