Block Stack QG

Retro falling-block puzzle

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Block Stack is a fast, satisfying take on the classic falling-block puzzle — drop, rotate, and slot the pieces to complete lines and keep the stack from topping out. Clean retro-futuristic visuals, punchy chiptune sound, and buttery gesture controls make every clear feel great. GAME MODES • Classic — the timeless endless mode. Clear lines, level up, and push your high score. • Hard — faster drops and rising speed milestones for serious stackers. • Adventure — clear pre-built structures to beat each level, with T-shaped and dot-shaped gaps to solve. The glowing blocks show your goal, and every level gets trickier. FEATURES • Smooth one-thumb gesture controls — slide to move, tap to rotate, swipe to drop. • Original chiptune theme music and crunchy 8-bit sound effects, with separate volume sliders. • A ghost preview and next-piece display. • Satisfying line-clear celebrations — go for the four-line BLOCKBUSTER! • Stuck? Watch a quick optional video to clear the bottom rows and keep going. • Play offline, anywhere. No account required. FREE TO PLAY Block Stack is free with banner ads. Prefer a clean screen? A one-time "Remove Ads" purchase takes them away for good. Drop in and start stacking!
