StackSlay

The most satisfying tap game on the App Store. Drop blocks. Build a tower. Each perfect drop triggers particle bursts, haptic feedback, and a color shift across your growing rainbow tower. HOW TO PLAY Tap to drop the sliding block onto the tower. Land it perfectly and the block stays full-size. Miss slightly and the overhang gets sliced off. Stack as high as you can before the block gets too narrow. PERFECT DROPS Nail a perfect landing and watch the block lock in with a satisfying burst of particles. Chain perfect drops for an even bigger effect. Every drop is matched with haptic feedback so you feel each landing. ZEN MODE No score. No game over. Just stack. When you miss, the block resets instead of shrinking. Build the tallest tower you want, at your own pace. GAME CENTER Compete globally on three leaderboards: Best Score, Best Height, and Best Streak. See how your tower stacks up against players worldwide. SHARE YOUR TOWER Every game over generates a custom share image of your actual tower — with its real block widths and offsets. Share your best towers to Instagram, TikTok, or Messages. COMPLETELY FREE No ads. No in-app purchases. No subscriptions. No internet required. Just a pure, satisfying stacking game.

Verdict
The clearest difference is in-app purchases: StackSlay at none against Mega Mantis's 16. StackSlay also leads on ads (none vs shown) and update cadence (every 3 days vs fortnightly). Mega Mantis's advantage is iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
