Trios is a new matching game where you try to match dots of the same color together, scoring the largest number of moves that you can before the game board fills up. Rows of dots will move together unless one or more of them is blocked.
While the game is free and comes with one mode, a 4x4 grid with three colors, other game modes are available as in-app purchases. These include grids of 4x4, 5x5, and 6x6, with combinations of four, five, and six colors, and each new mode costs $0.99. You can also purchase every mode together for $2.99.
You can download Trios for free right now from the App Store.
