How to Play Sumplete

Sumplete is a logic puzzle. You're given a grid of numbers, with a target sum beside every row and above every column. Your job is to delete the right numbers so that the numbers remaining in each row add up to that row's target, and each column adds up to its column target.

• 👆 Tap a cell to cycle it through three states: keep it (blue), cross it out / delete it (red), or clear back to neutral.
• 🎯 The number beside each row and above each column is the target the kept numbers must add up to.
• ✅ A target turns green when that row or column matches, and red if the kept numbers add up to more than the target.
• 🧩 Solve every row and column at once to win — each puzzle has a unique solution.
• 💡 Stuck? Use Hint for help, Reset to clear your marks, or New for a fresh puzzle.
• 📏 Choose your challenge: 3×3 Easy, 5×5 Medium or 7×7 Hard.

It's a relaxing, satisfying brain teaser — a bit like Sudoku crossed with mental maths. Great for sharpening your logic and arithmetic!
