Basic rules and scoring
Your job is to select the numbers to form the target sum before the timer runs out.
Your score per target sum is determined by the following factors:
How many numbers you used to reach the sum
How fast you assembled the sum
If you fail to form a sum and you run out of time, it’s game over.
This game allows you to continue a prior game if you quit between levels, but if you miss the timer only once it is game over and back to level one.
You can save your final score to the leaderboard if you reach a game over.
As you increase your level to higher levels with more blocks it can be helpful to use many low numbered blocks early in the level so that you clear out many of the blocks and have fewer blocks to search through to find the next match.
The game is suited for players who like number adding games.
