Sum Them Up

清除所有主板制造快速和的编号的瓷砖。

In Sum Them Up you must eliminate all the tiles of the board making quick calculations. Everytime you put a number on the board, if the sum of surrounding tiles ends in the target number all of them will be elminated.

To help you in your task you have 3 powerups:

- Bomb. Clear all the surrounding tiles.

- Mix: Change the remaining board numbers with other ones.

- Next: Skip the current target number and show the next one.

You can play Sum Them Up in three different modes:

- Classic. You have to clear the board in 100 movements or less.

- Time. You have 180 seconds to clear the board.

- Random. The 49 numbered tiles appear in a random position.
