About Hot Barrel Cats
Hot Barrel Cats is a lane tower defense with a merge rule. Drag cat gunners onto slots beside the path, upgrade their barrels, and merge two identical cats by dropping one on its twin.
Barrels overheat and need cooling — the same drag that places a cat pulls a hot one down. Wave previews show what is coming, and coins buy upgrades.

Tips & Strategies
- Cover two bends Place where the range circle touches two path bends instead of one straight stretch. Double coverage for the same coin.
- Max one before spreading A single fully upgraded cat outdamages three cheap ones at the same cost.
- Match the wave type Area barrels shred clustered waves; single-target cats handle bulky bosses. Read the preview before spending.
- Reposition during calm The preview shows the next wave. Move cats between waves — reacting mid-rush is too late.
