Block Master: Polygonal Puzzle is a free online puzzle game that swaps ordinary squares for irregular polygons you need to arrange across the entire playing field to clear each level. Instead of predictable block shapes, you get triangles, hexagons, and other multi-sided pieces that demand real spatial thinking to place correctly. It's a fresh spin on classic block-fitting gameplay that keeps your brain working from the very first move.

The game is split into difficulty categories, starting with straightforward layouts and gradually throwing trickier polygon combinations at you. There's no timer breathing down your neck, so you can take your time planning each placement — but the leaderboard means you'll want to keep pushing through levels faster than other players. Each completed stage feels genuinely satisfying, especially when a tricky polygon finally slots into that last awkward gap perfectly.

If you enjoy free online logic puzzle games, match-3 style challenges, or casual brain teasers that actually make you think, Block Master delivers. It's a solid pick for fans of block puzzle games, polygonal strategy games, and relaxing skill-based puzzles playable on both desktop and mobile browsers. Whether you search for free block fitting puzzles, online polygon puzzle games, or no-download brain games, this one covers all the bases without ever feeling repetitive.
