Clean all the leaves! Impossible Mode: 20-Minute Solo Route

What changes

Nothing about the map. Impossible is the same zones, waves and prices with a 20-minute timer instead of Easy’s 90 (Gamer Chad reads “only 20 minutes, confirm”). More gems per zone is the reward.

The route that finished with 29 seconds

Gamer Chad’s House clear on Impossible (Aug 22), with Leaf Bot:

1. Deploy the bot on the porch at 0:00. It cleans and sells for two minutes; by the time it rests he had $27 without buying anything.
2. Buy the $29.99 blower at about minute three, before any hand upgrades.
3. Porch and small zones first for the cash boost, then front yard and garage (he forgot the garage once and lost a minute).
4. Rooftop, then backyard: park the bot on the roof pile, blow the rest down.
5. Pool and maze path: the bot takes the pool while you clear the path; buy Width and Spread when you pass $42.
6. Farm twice, then the Molotov: burn the second pool wave and the basement piles rather than picking.
7. Basement: bot in the corner, Molotov on the pile, hand-pick the stragglers. Finished at 0:29 remaining.

Without a bot the same order works but the first three minutes are slower; mrsoft’s solo clear (Aug 19, 37K views) is the reference run.

Time sinks to cut

• Rake upgrades: never.
• Blower into corners: switch to hand for the last leaves.
• Open doors: a pile leaking into a finished zone costs a full re-clear.
• Watching the ending: the cutscene runs after the clock stops, so do not panic at 0:28.

Other maps on Impossible

The Mansion is faster than the House (its speedrun record is 2:48); Gamer Chad’s Hard clear took 15:12 with the blower fully upgraded, so a 20-minute Impossible is comfortable. The Gas Station’s back lot has three waves and the vent pays 3¢, so bring the blower fully upgraded before opening it. Difficulty timers and zone counts are on the maps page; the record run is on the speedrun page.
