世界とミッション
Moss Shell Taro is repairing three quiet bridges in a forest grove. Each bridge presents a small, authored set of stones with memorable names and a clear target. The goal is not speed: it is to notice relationships, make a plan, and choose a stable combination that leaves the bridge balanced.
The short campaign keeps the same friendly rules while changing the target, stone set, and useful combinations. Later groves ask for more deliberate comparison and make decoy stones more tempting, so players learn to check the whole tray rather than grabbing the first plausible answer.
ゲームの仕組み
Select stones from the tray to place them on the right pan, then choose Check balance. The left pan shows the fixed bridge weight and the right pan shows the selected subset. A wrong combination is safe to clear and try again.
There is no timer, account, purchase, or advertising request. Progress and best checks stay in this browser. The same readable Main, Stage, Battle, and Result flow works with touch, mouse, and keyboard input.
遊び方
- Start a round and read the target shown for the current grove.
- Inspect the names and weights on every stone before selecting one.
- Choose a subset whose total matches the bridge target, then check the balance.
- Clear the pan and try another combination when the result is not steady.
攻略のヒント
- Look for pairs that add up to the target before testing larger combinations.
- Use the displayed weights to eliminate stones that are already too heavy or too light.
- Keep the remaining tray in view; a decoy that helps one partial total may block the final subset.
- Treat each grove as a short lesson in subset planning rather than a race against a clock.
進行と難易度
The first grove introduces the scale, named stones, and direct target matching. The second grove adds more tempting alternatives and asks for a clearer comparison plan.
The third grove combines the earlier choices into a compact mastery check. Every grove remains replayable, and a calm retry helps players understand why a subset succeeds or fails.
開発者メモ
Balance Grove uses deterministic authored targets, visible arithmetic, responsive Main/Stage/Battle/Result screens, localized controls, and gentle retry feedback. Its puzzle feedback is for play and local progress, not a formal ability assessment.
