CONTROLS
Action
Player 1
Player 2
Click a key cell and press the new key. Esc cancels. Touch controls (D-pad · SET · FAST) are always available on mobile.
Move with WASD or the arrow keys, or a plugged-in DualSense / Xbox pad. Space (or ✕ / A) arms the tile under you; press it again to spring the trap on whatever stands there.
Capture green cubes to leave charges behind — E (or ▢ / X) detonates every charge in a 3×3 burst, and chained greens leave fresh charges.
Never trap a dark cube. Let those roll off the edge. Each one you capture tears a row off the stage — and every full line of grey cubes you let escape does the same.
Hold Shift (or R2) to hurry the wave. Clear a puzzle flawlessly and the stage grows back.
Advanced: align yourself exactly on a grid-line and you can slip between two cubes as they land. Practise it — the final stage demands it.
A love-letter to Sony's Intelligent Qube / Kurushi (1997).
Puzzle RNG, roll timings and cube ratios ported from
adeyblue's PS1 disassembly.
Built in TypeScript on three.js WebGPU. Everything you hear is a
WebAudio oscillator — no audio files ship with the game.
If the monolith crushes you tonight, I promise it didn't cheat.
Runs on the PS1's own random number generator, 30% mirror rolls, real cube ratios and
frame-accurate roll timings. If a cube is about to land on you, the seam between two tiles is
exactly wide enough to live in.
