DropSum will put your maths skills to the test as you have to add the numbers in this complex puzzle game.
Select between basic mode, arcade mode and timed mode.
In timed mode, if the timer hits the top of the screen, your tile will drop automatically.
In arcade mode, you can collect power-ups to help you throughout the game.
You will be given a number in each game.
Try to add the tiles you drop to equal the value of the number you have been allocated in each game.
Get the tiles to add up to the required number in rows and columns.
Use the mouse to decide where you want to drop your tile and click the left mouse button to drop it.
When the tiles complete the required number, they will change from grey to blue.
Do the same again to change the tiles from blue to yellow, and then from yellow to red.
When the tile is red it is ready to disappear. Getting the tile to add yet again to the required number will make it disappear.
The bigger the groups of tiles you get to add to the required number, the more points you will receive.
Collect stars for bonus points.
At the end of the game you will not only be awarded points but also be given your brain size and reaction time.
