Blockslam is a block puzzle built for people who love the genre but are tired of the ads. Drag pieces from your hand onto the board, fill complete rows and columns to clear them, and stack up combos for massive scores. Easy to learn, endlessly replayable — and never once interrupted by an advertisement. NO ADS. NO IN-APP PURCHASES. NO TRACKING. Blockslam has zero ads, zero paywalls, and collects zero data. It doesn't even connect to the internet. Just the game, the way it should be. FIVE BOARD SIZES Play the classic 8×8, or change the challenge entirely with Tiny 6×6, Small 7×7, Big 9×9, and Huge 10×10 — each with its own high score. CHASE COMBOS Clear lines on back-to-back moves to build streaks and watch your score multiply. The scoring is tuned to feel just right. UNLOCK AS YOU CLIMB Earn new color palettes and board skins by pushing your Classic high score higher — from your first thousand points to serious milestones. EARN ACHIEVEMENTS A full set of tiered achievements tracks your best combos, lines cleared, board clears, and more. MAKE IT YOURS Custom mode lets you pick the board size and toggle exactly which pieces appear — a relaxed sandbox, your rules. BUILT RIGHT • One free revive per run when you get stuck • Satisfying crush animations, particle effects, and haptics • Run history and personal stats • Native, lightweight, and built entirely with Apple frameworks Whether you've got thirty seconds or thirty minutes, Blockslam is the calm, satisfying, ad-free block puzzle that's always ready when you are.
