About

BLOCK45

Features
Read full description

Think you've played every block puzzle? Think again. BLOCK45 breaks the one rule every block game shares: gravity flips every turn — down, then to the side. The board never falls the same way twice. Read the shift, group 6+ same-color blocks to clear them, and set up chain reactions that wipe the whole board in a single move. A fresh, brain-bending spin on a genre you thought you knew. ■ WHY IT'S DIFFERENT • Gravity flips every turn — a mechanic you won't find in any other block puzzle. • One well-placed piece can trigger a board-clearing chain. • Easy to pick up, genuinely new to master. ■ HOW IT PLAYS • Group 6 or more same-color blocks to pop them. • Each clear drops blocks into the next — chain them for massive combos. • 6 stages of rising difficulty, more colors, and faster drops. ■ COMPETE WORLDWIDE • Weekly global leaderboards — by country and by nation. • Reach the TOP 20 and your linked YouTube, Instagram & TikTok show up for players worldwide. • Leaderboards update daily, reset every Monday. ■ MAKE IT YOURS • Design pixel-art emblems and show them off on your profile and the leaderboard. • Hundreds of color combinations to build with. Free to play. Simple to learn, genuinely new to master.
