Game rules:

Swap: If two fruits in the neighborhood are checked, they will be swapped. At this moment, if the swap is successful, the two fruits will be removed; otherwise, the swap will be canceled.

Remove: When the swapped fruits are three or more than three same ones horizontally or vertically, the same fruits will be removed and some new ones will be dropped from the top. On the contrary, if the number of the swapped fruits is not enough, the two checked fruits will be back to their original position. Every time, player can get some scores.

Chain: After the fruits are removed, some new fruits will be dropped from the top to fill up the blank grid. When the dropped fruits are paired up with the original ones horizontally or vertically, these fruits will be removed. This is one chain reaction. Meanwhile the chain reaction occurs sporadically, if the player is lucky enough. Accordingly, player also can get some scores.

Reset: If there is no any fruit which can be removed at all, the game will be reset and there will be some new fruits.

Pass condition: When getting enough scores, the player can get into the next level.

Level introduction: After getting enough scores, the player can get into the next level. What’s more, in every new level, there are some new fruits; relevantly, it is more and more difficult to be passed.
