How high can you stack? STAK is the one-tap tower game that's impossible to put down. A block slides; you tap to drop it. Nail the center for a PERFECT - miss, and it's over. Simple to learn, brutal to master. Then it gets deep: GOLD RUSH - chain 10 perfects in a row and the tower ignites: 3x diamonds until you slip. GOLDEN BLOCKS - every 15th block is gold. Land it perfectly for a jackpot. PERFECT GAUNTLET - hit a 15-streak and the next blocks go double-speed for huge bonuses. High risk, high reward. GLOBAL LEADERBOARD - every score is server-verified, so the rankings are cheat-proof. Climb to #1. DAILY CHALLENGE & QUESTS - one seeded run a day that's the same for everyone, plus 3 fresh objectives for bonus diamonds. Build your streak. DIAMONDS & SKINS - earn diamonds every run and repaint your tower with unlockable skins: Neon, Sunset, Gold, Aurora and more. Free. Instant. No account needed. Just one more go.
