Domino effects can be fun. That's the basis for this game called "Icy Gifts." There are cubes of ice that will explode upon melting, and when they explode in to others, the others will explode as well. There are also gifts that can be grabbed while the explosions are occurring. All of the controls are with the mouse. Left click in a strategic spot to try and blow up all of the ice on the screen. Hover your mouse over the gifts to grab them. Keep going and see how many levels and upgrades you can get. Each level gets more and more difficult.
