BlockStack — one-tap tower stacker built for the small moments. TAP TO STACK A block slides over your tower. Tap to drop it. Land it flush — perfect hit — and the multiplier climbs. Miss center and the block is trimmed to the overlap. Run out of space and the tower falls. COMBOS UP TO x25 NICE → GREAT → PERFECT → GODLIKE. Chain perfect drops up to a x25 multiplier. Every combo tier ships with its own callout, haptic, particle burst and sound. 12+ FULL-APP THEMES Sunny Sky, Bamboo Forest, Ocean Depths, Cyberpunk City, Galaxy Master and more. Themes replace the entire visual layer — blocks, background, music, buttons — and unlock as you climb the leaderboard. PERKS, MISSIONS, DAILY STREAKS Spend coins on perks that bend the rules: wider blocks, slower speed, double starting points, extra revives, perfect-radius assist. Daily missions and a 7-day streak chest keep you coming back. GAME CENTER LEADERBOARDS Climb the global high score. Compare best streaks with friends. Free to play. Optional coin packs available. No subscriptions, no recurring billing. Privacy Policy: https://codecake.app/privacy-policy/
