The falling block puzzle game... expanded. Arrange strange five-block pieces, clear lines, and survive the escalating chaos in this fresh twist on the classic falling-block formula. Instead of traditional tetrominoes, every piece is a pentomino: unique shapes made from five squares. That single extra block changes everything: • tighter fits • trickier decisions • huge combo potential • wonderfully catastrophic mistakes • Easy to learn, surprisingly deep, and dangerously hard to put down. Features • 18 unique pentomino pieces • Fast-paced endless gameplay • Combo scoring and line clears • Clean minimalist visuals • Quick restart for “just one more run” Can you keep the board under control once the weird shapes start falling?

Verdict
The clearest difference is in-app purchases: Pentris+ at none against Chessigma's 2. Pentris+ also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 80%). Chessigma's advantage is ratings volume (87 vs 3) and iOS requirement (15.0 vs 18.2). On price, update cadence, ads and monetization model there is nothing between them.
