In the game Match Sum, you have to combine white numbers to match the sums shown in colored cells. Every number on the playing field can be used just once.
The complexity of the puzzles grows up to the 100th level.
In the primary game mode, you don't need to rush, but there's also a challenge mode where you must solve as many puzzles as possible within 120 seconds.
How to play
Use the mouse to choose white numbers with a left click, and then select the matching colored sum.
If needed, you can deselect numbers by clicking on them again.
It's also possible to pick numbers that have already been used so you can use them for another sum.
