About this game
Toggle the named signals on or off. Every clue must be true at the same time; a single change can alter the meaning of the whole ledger.
How to play
Unlike a standard number grid, Logic Ledger makes relationships—not arithmetic—the board. Each daily case has one intended solution.
A GameMind Signature challenge
This original entertainment puzzle combines more than one kind of reasoning in a short daily session. Choose Easy, Medium or Hard, finish the board, share the result and challenge a friend to the same seeded puzzle. No account or sign-in is required.
GameMind games are entertainment, not medical tests, IQ scores or diagnostic tools.
How to play Logic Ledger
Logic Ledger gives you named signals that can be on or off. The written clues describe how they relate. Build the intended configuration by making all the clues agree at the same time.
- Read the full clue list before changing the signals. Every signal begins off.
- Select a signal to switch it on or off. Start with a clue that directly names a signal's state.
- Follow matching and opposite relationships, then check any clue about the total number of active signals.
- Choose Audit ledger to check the configuration. Use Resolve one signal if you want help with one unresolved position.
Plan your next move
Translate each relationship into a small fact. If A is on and B is opposite A, then B must be off. If C matches B, C is also off. Carry that chain through the clues before making an unrelated guess.
A count clue is especially useful after several signals are fixed. Compare how many are already active with the required total. Recheck the whole network after a change because a single signal may appear in several clues.
Does Audit ledger change my switches?
It checks your current arrangement and reports progress. You can keep adjusting an incomplete arrangement. A fully correct arrangement finishes the game.
Do hints affect the result?
Resolve one signal supplies a correct state and counts as a hint. Hints reduce the finishing score, so use each revealed state as a starting point for your next deduction.
