## What is Cherry Sum?

Think through every branch and complete the puzzle.

Cherry Sum is a quick brain puzzle built around branching logic, simple number rules, and increasingly challenging stages. Follow each connection, determine the correct value, and fill every empty circle.

Each circle follows one of two rules:

• One circle below: copy the same number.
• Two circles below: add both numbers and enter the ones digit.

The rules are easy to learn, but each new layout gives you another logic challenge to solve. Study the branches, reason through the sequence, and complete every circle at your own pace.

Features:

• Simple branching logic rules
• Quick puzzles for short breaks
• Randomly generated layouts
• Increasing difficulty across stages and ranks
• Optional hints through rewarded ads
• Guided tutorial for new players
• Sound effects and background music controls
• Progress saved locally on your device
• Designed for both iPhone and iPad

There is no account registration and no in-app purchase.
