About Keep Prime Numbers
Remove all the blocks to make the composite number going out but keep the prime number. Click or tap the unused block to drop the composite numbers.
How to Play
Click on the tiles that are composite to eliminate them from the grid. Do not select the primes as they must be kept on the grid. Use your understanding of prime and composite numbers to thoughtfully choose which numbers to remove. Advance by eliminating all composite numbers from each stage. Watch out for the challenge as you progress through the levels. Work on your math skills to improve your score.
