Toon Blast is an amusing game that I can recommend for children too. It is about achieving certain goals in an arrangement of colored blocks. Adjacent blocks of the same color can be removed. There are additional difficulties and extras such as missiles and bombs etc.
If you don’t like to play alone, you can also join a team via the Internet to master a few challenges as a group.
