Grow a neon snake through a block puzzle — then harvest it. Everything multiplies. Snake Stack is a block puzzle with a living center: drag pieces onto the 8×8 board, touch your snake to grow it, and clear lines straight through its body for triple points. The longer the snake, the bigger your multiplier — up to ×10 on every single point you score. But the snake has a mind of its own. It hunts the apples your harvests grow. It slithers between your moves. Bury it and it suffocates. Feed it, route it, harvest it — and it pays you back tenfold. ◆ EVERYTHING MULTIPLIES — snake length multiplies all scoring, up to ×10 ◆ HARVEST — clear lines through your snake for triple points and fresh apples ◆ THE HUNT — the snake stalks food by itself; help it eat and get paid ◆ COMBOS — chain clears against a tightening clock, land CLUTCH saves ◆ THE DAILY — one attempt, the same board as the whole world, your global percentile the moment you finish ◆ STREAKS & SHIELDS — finish all three daily goals to bank a streak shield ◆ 8 SKIES — the world changes color as your score climbs; collect them all ◆ EARNED SKINS — Ice, Vapor, Solar, Ember, Nebula. Gold and rainbow can't be bought — only grown ◆ UNDO — one take-back per run, because misdrops happen
