Triple Sum Challenge - Mental Math Game

How to Play and Win

Find triples of numbers where one number equals the sum of the other two.

Players take turns selecting 3 numbers from their board
If the triple is valid (a + b = c), those numbers are removed
The player earns points equal to the sum of the triple
The game ends when no valid triples remain
The player with the lowest remaining sum wins

Strategy: Try to remove high-value numbers early to minimize your final score. Look for multiple triples that share numbers to maximize your moves.
