"Complete an Odyssey in under 1 hour"

- BTD6 description

 is an Achievement in BTD6, introduced in the 20.0 update. To earn the achievement, the player must complete an Odyssey in under one hour; collecting it grants 100 Monkey Money, a Glue Trap, and a Camo Trap.

Strategy
The only way to adequately complete this achievement is play on only any Easy Odyssey. It is mathematically impossible to try it out on a Hard Odyssey because most Odysseys contain islands where there are many rounds long. Most Odyssey Islands are formatted such that they start on any early round between Rounds 1-6 and end on any round between Round 40 to Round 95, at least for the majority of Odyssey Islands.

The average island beaten with an average anti-stalling strategy will take a minimum of 5 minutes at best for games going from anywhere between any pre-picked early round to Round 40. On the other hand, the average island beaten the same way would take much longer for games where rounds go beyond Round 80; the average anti-stall strategy will take a minimum of 15 minutes to beat any game between pre-picked early round to Round 80, while going beyond that can take up to a minimum of 25 minutes.
