Game Mode:

1. Basic Mode
Non-competing mode which you can play comfortably. Total 9 rounds, which have 4 innings each. The difficulty of the puzzle increases as the round goes on. 

The time spent and the number of moving blocks decide the number of stars which you can get.

You can go to the next round only if you have cleared the previous one. Get the most stars by playing the rounds again and again.

By playing this mode, you can get used to the fifteen puzzle even though you do not know it at all. If you are a master of it, go for getting the most stars!


2. Pro(Master) Mode
Competing mode. You can play with others through Game Center.

You should clear all the 9 rounds within a time limit (basically 30 seconds).

You can use the remaining time at the next round if you clear a round quickly. This mode is for masters, which provides the best thrill and tension.
