An 8-bit number puzzle played as a race. You and the machine work on the same board, the computer places one correct mark every few seconds, and whoever completes it first takes the round. Read the cabinet labels below.
1P · Race the machine
Three rivals: Rookie on 6×6 at 7.0 seconds per mark, Ace on 7×7 at 4.2, Legend on 8×8 at 2.6. Two segment bars show your progress against the computer. Tap a cell to fill it with your pixel colour, tap again to keep it open with yellow corners, once more to clear. No number repeats among open cells in a row or column, filled cells never touch side by side, and the open cells stay joined.
2P · Pass-and-play duel
Pick a size from 5×5 to 8×8. Player one solves, hands the device over, then player two solves the same board. The faster time finishes first, and 20 duels stay on record.
+1 · Workshop
Points come from every solved race and duel. Scanner adds a hint charge per race, Freeze ray stops the rival for six seconds once per race, and Sticky keys makes rivals a tenth slower per step.
FX · Skins
Six pixel skins for filled cells, from Arcade cyan and Sun chip to Lime glow, Grape soda and Ghost white, unlocked by finishing ahead of the machine.
TR · Trophies
Eight trophies, from Player one and Ace down to Legendary and Collector.
HI · Race log
Totals for races, firsts, solved boards and duels, plus your last 20 runs with rival, size and time.
SY · Setup
Haptics, how to play and a save wipe. Pixel stars fly left, a neon floor runs to the horizon and a scanline rolls behind the menus; switch Background animation off in Setup for a still screen.
