About this game
Gem Dojo wraps its gem board in a ninja story. You train in a secret dojo, and matching gems is presented as the martial art being learned. The goal set out by the developer is to beat rival ninjas and climb through the dojo's ranks until you are a master.
Swapping gems into matches does two things here. It clears them, and it charges up your ninja abilities, which you can then turn on opponents. Combos are mentioned, as are hidden techniques that become available as you progress, although none of them is named or explained. The puzzle challenges are said to get trickier as you go, and matches also win bonuses.
That is close to everything the developer says. No level count or list of abilities is given, so expect to learn the details by playing.
How to play
Swap gems so that three or more of a kind line up, which clears them and earns bonuses. Each match also feeds your ninja abilities, building up their charge. Use those abilities in fights against rival ninjas, and keep winning to rise through the ranks of the dojo. Look out for hidden techniques that open up along the way.
Controls
The developer does not list the controls for this game. It runs inside the frame above, so a click or a tap on the game is the place to start.
Tips
Matches are your energy source as well as your way of clearing the board, so a steady run of them keeps your abilities charged for the next fight. Combos are mentioned as part of the game, so look for chances to chain matches. Expect the puzzles to get harder as you rank up.
