How to play

Each outlined group of n cells holds the numbers 1 to n once.
The same number never touches itself, not even diagonally.
Click a cell, then type. Empty cell: the number is placed. Same number again: removed. A different number: both become notes. Pressing one of the notes removes it, and when a single note is left it becomes the number.
Score: every game starts at 1000. Each wrong number costs 50, each note 10 and each Help 100. With no errors, notes or help it's a perfect game, shown by the ★ badge next to the clock.
Help fills in one correct number: the selected cell, otherwise a wrong one, otherwise the easiest empty cell. Check crosses out every wrong number and keeps checking each new entry; press it again to turn checking off.
Shift+number toggles a note. F toggles fullscreen, arrows move, Backspace erases, Ctrl+Z undoes.
