What is BONK! The Mole Show?
BONK! The Mole Show (BONK! for short) is a pixel-art whack-a-mole roguelite game for PC and Steam Deck, made by RantGames, a solo developer from Spain. A carnival mole machine scrolls toward you; you only slide the hammer between columns and it BONKs by itself when a row reaches the line.
Between hits you draft hammer modules, special moles, prizes and chemistry recipes, so one good BONK can set off lightning, bombs and golden chains across half the machine. Six fairs, six bosses, an Endless mode and a daily challenge. Try the free demo on Steam in the Steam Winter Sale 2026.
How it plays
Same controls from minute 1 to minute 20. The only question: which column gives me the best next BONK?
Auto BONK
When a row reaches the line, the hammer BONKs its hole by itself. Read the rows coming up and stand in the right spot.
Chain it
Build hammer modules, special moles, prizes and chemistry. One correct BONK sets off a chain across the machine.
Build your machine
Every run is a new machine. Level pieces up, mutate them and link them with curated chemistry.
Hammer modules
Four slots. Wide Head, Double Tap, Boomerang, Fuse Head... each one changes where and why you stand.
Special moles
Tesla zaps its neighbours, Bomb blasts the area, Piñata rains golden moles. Normal moles are the fuel of every chain.
Chemistry
Curated recipes between two pieces you own. Tesla + Bomb = OVERLOAD. Mutate both and they RESONATE.
Prizes
Rule-breaking prizes: a Black Hole that swallows rows, a pinball on the board, a Joker that becomes any mole.
Keep the crowd happy
The Audience is your life bar. Escaped moles bore them, big chains win them back. No HP, no shooting, no dodging.
Endless (ENCORE), daily and more
Endless mode (ENCORE), a daily challenge with medals, Heat levels 1-5, a Boss Marathon, cosmetics and a Steam Deck friendly pad setup.
