There are various modes available, including a [training] mode with the state names and boundaries, a [basic] mode testing only state names, and an [expert] mode without hints. When you're stuck on finding the location of a state, use the [Assist] function. It will help you to navigate the correct location without hassling yourself. However you will be added a 30 seconds penalty when you use the [assist] function. If you want to achieve a higher ranking, it'd better not to use this function.

Binary logic, graded by the technique each board actually needs. Fill a grid with two symbols under three rules: never three of the same symbol in a row, an equal count of each per line, and no two identical rows or columns. Tap a cell to cycle it. That is the whole game. DIFFICULTY THAT MEANS SOMETHING Boards are labelled by the DEEPEST solving technique they genuinely require — Dawn, Day, Dusk and Night — computed by the same deterministic solver that proves each board has exactly one solution. Dawn, Day and Dusk are solvable by pure forward deduction: no hypotheticals, no guessing. Night asks for exactly one bounded "what-if" chain that resolves in a few steps, never open-ended trial and error. We say that precisely rather than promising a "never guess" that a hard board would contradict.
