Tetravex DS is a remake of Tetravex for the DS. It is a puzzle game where you try to match the numbered edges of the tiles with the edges of the other tiles.
- Dimensions of board can be 2x2, 3x3, 4x4, 5x5, or 6x6.
- Move all tiles on the solution board at the same time using the D-Pad.
- Tiles are coloured as well as numbered.
Move all the tiles from the bottom screen to the top screen to win. You can only place a tile on the top screen grid if the numbers on the tile match up to the numbers on the tiles next to it (unless there are no tiles).
A border around the tile will tell if it is allowed to place the tile: red for not allowed, while green is okay to move.
You can only acquire hint before starting to place tiles.
