What a clear pays
A standard map runs 25 waves on Easy, 35 on Medium, and 40 on Hard. Beating the boss pays coins and EXP. Many maps also pay a difficulty skin, sometimes a hero, and a modifier with a printed drop rate.
Quiet Quarry, recorded as added 13 June 2026, is the clean example. It is a crystal cave with an elliptical path that splits and rejoins. The wiki map index labels it level 30+ and 4 skulls.
| Difficulty | Named reward | Listed coins | Listed EXP |
|---|---|---|---|
| Easy | Explorer skin for Scientist | 19 | 12.3 |
| Medium | Amber skin for Discount Dog | 31 to 36 | 22.1 to 25.5 |
| Hard | Army Ants skin for Nuki Launcher | 46 to 60 | 33.3 to 42.5 |
Defeating the Minecart Mimic is listed for the Miner Kid skin on Kart Kid. The Quiet Quarry modifier is 5% Easy, 10% Medium, and 20% Hard.
Knoddy's Resort, from the Robot 64 crossover, pays Beebo on Easy, a Knoddy's Resort skin for Beebo on Easy as well, Candy Aquarium on Medium, and Cyan Neon on Hard. It has more than one round theme, and night never falls on Easy. On other difficulties the sun sets at wave 28, or wave 33 on Hard.
Level gates that disagree
Use the in-game elevator when these two public indexes do not match:
| Map | Wiki map index | September 2026 database table |
|---|---|---|
| Volcano Valley | Level 15+, 3 skulls | Level 5+, 3 skulls |
| Desolate Desert | Level 5+, 2 skulls | Level 10+, 2 skulls |
Skulls match. The level does not. Other cards in the wiki index agree with themselves: Facility Frenzy is level 10+ and 2 skulls, Radiant Reef is level 10+ and 4 skulls, Destiny's Dawn and Quiet Quarry are level 30+ and 4 skulls, Sunken Sanctum is level 30+ and 5 skulls.
Game passes that unlock a hero
