Stranger, not faster. Blocks fall. Lines clear. You already know this game - until the bag starts changing. Every cleared row earns credits, and credits buy cursed relic-cards that bend the rules of the game itself. Your hand of relics survives death; only the board resets. (That's the roguelite part.) Most block games get harder by speeding up. Ominomicon gets harder by changing what falls: every level introduces a stranger piece and quietly retires a familiar one. By the deep game you're stacking nothing but pentominoes - on a board that periodically flips upside down. FREE TO PLAY, PROPERLY The free version is a complete game: 12 of the 20 relic-cards, every mechanic, endless runs, global leaderboards One small purchase unlocks all 20 cards, forever - shareable with your family No ads, no subscriptions, no energy timers, nothing consumable. Ever. THE RULES ARE FOR SALE 20 relic-cards: bombs, second holds, bag exorcisms, time running backwards Exclusive pairs force real choices - no two runs build alike Your hand carries through death; only the board resets UNSTABLE GRAVITY Every minute or so, gravity inverts and pieces fall upward The power grid flickers just before it hits - learn to read the lights Counter it with Gravitonics or ride it with Surge Rider for a triple score multiplier A ROSTER, NOT A SPEEDOMETER 29 shapes: from the humble monomino to the full pentomino bestiary Level 1 gives you twelve friendly pieces; the endgame is eighteen pentominoes only Speed only climbs after the roster finishes mutating POLISHED TO THE LAST PIXEL Global leaderboards via Game Center - all-time and weekly, every score cryptographically sealed Dark synthwave soundtrack; the board glows on the beat One-thumb portrait controls with haptic feedback Every visual effect - flicker, shake, glow - is adjustable or can be turned off entirely No tracking. Fully playable offline, always. Free to try. One purchase to own. Play forever.
