Mash-ups seem to be a good way to make a creative and potentially enjoyable iOS game. This mash-up, Rock-a-Tac, is a mix between simple classics tic-tac-toe and rock-paper-scissors. This confrontation of double hyphenated games includes a tic-tac-toe board being filled up by either rocks, paper, or scissors.
The win a game of Rock-a-Tac, users must fill a row with either rock, paper, or scissors. But, unlike tic-tac-toe, there are no ties in Rock-a-Tac. When a board is filled with no winner, rows are won by rock-paper-scissor elements.
There are both single and multiplayer modes in Rock-a-Tac. The single player mode pits players against an AI opponent while multiplayer can be against friends or random opponents via Game Center.
For mixup of two very simple games, the graphics look quite interesting. There are various arenas to do battle on and different looking teams to compete with (including heroes and villains). There are both free and paid versions. The paid version is $0.99 and includes no ads.
