This level occupies the map slot MAP20. For other maps which occupy this slot, see Category:MAP20.

MAP20: Master Computer is the twenty-second map of Hell To Pay. The discrepancy between map slot and progression number is because the MAP31 and MAP32 are inserted between MAP15 and MAP16 as part of the regular progression, instead of being secret levels.
