!Egg Chess (A board game like,Tic-Tac-Toe,but smarter)
A game like Tic-Tac-Toe, but instead of using circles and crosses uses eggs in different forms.
On a 3×3 board, players take turns either adding an egg to an empty square, or changing an egg. The egg can be a whole egg, broken egg, or empty egg.
•A whole egg can turn into a broken egg or an empty egg,
•A broken egg can turn into an empty egg,
•And an empty egg cannot be reformed.
The player who gets three of the same form of eggs in a line on the 3×3 grid wins.
The game is played in turns. You can play against the iPhone or against another person.
If it is your turn, tap an empty square to place a new piece or tap any existing piece to upgrade it. You may tap more than once, but each turn you may change only one aquaria.
TIP: You can also change your opponent's pieces!
Hope you enjoy the new generation of Tic-Tac-Toe :)
