MIT Mystery Hunt 2021/⊥IW.giga
⊥IW.giga is one of the rounds of the 2021 MIT Mystery Hunt, with the first puzzles unlocked when teams reach a JUICE level of 100. Notably, it begins with the metapuzzle for the first sub-round already solved.
Description[edit | edit source]
On the round page, the first subround, ⊥IW.giga, is situated in space, with each puzzle appearing as an asteroid. The second round, ⊥IW.kilo, is situated in a planet, with each puzzle appearing as an island. The third round, ⊥IW.milli, is situated on a circuitboard, with each puzzle appearing as a circuit. Once the second subround is unlocked, navigation between the subrounds is possible via a magnifying glass that can zoom in and out.
In the projection device, ⊥IW.giga appears as a series of space rocks and air-locked chambers, with puzzle givers being aliens. The ⊥IW.kilo round took place in a normal classroom setting, with puzzle givers being clean room technicians. The ⊥IW.milli round took place on a circuit board with puzzle givers being robots.
[edit | edit source]
The navigation puzzle in the projection device involved a multi-state maze. Upon solving some puzzles, devices that allowed for changing the size of the player character unlocked. Many actions, such as going through certain tunnels, using size-changing devices, and getting puzzles from NPC's, required players to be in a certain size.
List of Puzzles[edit | edit source]
Puzzles in ⊥IW.giga are divided into three sub-rounds by size, with a single puzzle carrying over to the next level down as a meta.
