Octagons Free

The Octagons are a fantastic puzzle game that requires luck, skill and strategy.
Arrange the Octagons in a grid of 5×5.
Earn points by the valid combinations (horizontal, vertical or diagonal) depending on the sum of numbers.
When the sum of numbers are equal with zero, the octagons will be removed from the grid.
The game ends when there is no more space for new octagons.
