Gem Dojo is a ninja-themed match-3 puzzle game where you swap and align colorful gems across increasingly challenging grid-based levels. Each match charges your ninja abilities, letting you trigger powerful combos that clear the board and deal damage to rival ninjas standing in your way. The core loop is simple to pick up but demands real strategic thinking as the puzzles get tougher.

What sets Gem Dojo apart from standard jewel-matching games is the ninja progression system. Matching gems in quick succession builds combo chains that unlock hidden dojo techniques, giving you edge-of-your-seat moments when a perfectly planned sequence wipes out a tough opponent. You need to think several moves ahead, prioritize which gems to swap, and manage your special abilities wisely. The vibrant gem colors make it easy to spot potential matches fast, but the real skill is setting up chain reactions.

Gem Dojo is a great fit for fans of casual match-3 games, jewel puzzle games, and anyone who enjoys a bit of ninja flair mixed into their brain teasers. If you regularly play free online match-3 games, jewel swap puzzles, or colorful casual puzzle games with progression systems, this one belongs in your rotation. No download, no sign-up - just open the browser and start matching gems against the dojo's toughest ninja rivals.
