HARDSUM

HARDSUM is a fast, satisfying puzzle game that turns simple addition into a true test of logic. Each challenge gives you a 3x3 grid. Every cell contains multiple number options, but only one choice in each cell leads to the correct solution. Your goal is to find the right combination so every row and column matches the target sum. HARDSUM is easy to understand in seconds, but every puzzle pushes your focus, pattern recognition, and reasoning a little further.
