3. Crash It

6. Mystery Paradise

Mystery Paradise

In Mystery Paradise, your objective is to remove the colored background tiles by arranging the balls. Match three or more of the same colored balls to remove them and the background tile(s) from the board.

If you make a match, you continue with the balls already on the board. But if you make a move that does not make a match, more balls will appear. This is important to remember because in order to make matches, balls must have a direct path to each other. Clear the tiles and move onto the next challenging level in Mystery Paradise.

7. Cube Crash

Cube Crash is a match-three game with a fun twist. Yes, you need to click on three or more matching colors to remove the tiles from the board.

As you move your mouse over the blocks of tiles, you will see how many points that click will get you towards your goal. So, listen to the jazzy music and strategize your matches as you work to complete each level.

Continue playing until you reach the level goal to move forward. If the blocks reach the top, the game is over.
