The Time column displays the amount of time (in seconds) the Mystery Master program took to solve a puzzle in Fast mode. Fast mode updates the display only when a solution is found, and is so fast that all times are rounded up to the nearest second. If there are two times given for a puzzle, it means the program needed to make one or more assumptions, so the second time gives the total amount of time needed to search all possible assumptions.

All times are for a Pentium 4 3.4GHz with 1 gigabyte of memory.
