About

Block Square

Features
Read full description

Block Square is a block puzzle that's easy to learn and hard to put down. Drag the pieces onto the 8×8 board and complete rows and columns to clear them. The game ends when none of your pieces fit anymore — so plan every move and try to beat your high score. KEY FEATURES • Three difficulty modes: Easy, Normal and Impossible — each with its own high score. • Spins: rotate pieces to make them fit. Earn more spins as you clear rows and columns. • Score multipliers: a temporary bonus that grows on every clearing round, plus a permanent multiplier when you clear the whole board. • Polished look with colorful blocks and smooth animations. • Play offline, anytime. Your game is saved automatically so you can continue later. • No ads and no tracking. • Available in 10 languages, on iPhone and iPad. HOW TO PLAY 1. Drag one of the three pieces onto the board. 2. Complete a full row or column to clear it and score. 3. Use spins to rotate pieces and open up space. 4. Survive as long as you can and beat your record! SUPPORT THE DEVELOPER (OPTIONAL) Block Square is free. If you enjoy it, you can buy me a coffee inside the app — it's entirely optional and unlocks a permanent thank-you badge: "You're part of this." Thanks for playing!
