Numbers & Logic

Numbers & Logic

No pretty pictures and no sudden sounds here; there is a grid, some numbers, and one rule you have to hold until the end. This section sits in the middle of the shelf on purpose, because it is not a starting point: number boxes ask you to keep a rule in your head for several minutes, and that is tiring if you are not used to it. It is, however, the best place for a quiet session after work, since nothing moves and no clock is running. Every title here keeps the finished arrangement in your browser, so you can leave in the middle of a row and come back tomorrow.
