BLOCK45: Gravity Block Puzzle

Gravity flips every turn. Play instantly — no sign-up — and see yourself on the global leaderboard, updated every hour. Can you crack the TOP 100?

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.
