Summa: Number Puzzle Game

Combine numbers to hit the target — just a calm puzzle to sharpen your mind at your own pace. Different difficulty tiers to master. Stay tuned for future updates.

Summa is a calm, elegant number puzzle — a quiet game of placing the right numbers in the right order.

Each level gives you a target and a template: a row of empty slots joined by fixed math operations. From a small pool of numbers, you drop one into each slot so the whole expression lands exactly on the target. The trick is working out which number goes where. Easy to pick up, satisfying to solve.

• Multiple difficulty tiers, from gentle warm-ups to expert head-scratchers • Fully offline — play on a plane, on the subway, or anywhere with no signal • A minimalist, distraction-free design built for focus • Progress syncs across your devices with iCloud

A gentle brain workout for every age: a playful way for kids to build number sense, a rewarding daily exercise for older minds that love to stay sharp, and a genuinely clever challenge for anyone who enjoys a good math puzzle.

Five minutes or fifty, Summa is a relaxing way to spend them.
