Free to play, with no ads, no in-app purchases and no tracking. No account, no internet connection needed: just you, Dr. Jo and a lab full of runaway monsters.

Dr. Jo's lab experiment went wrong, and now little monsters are multiplying everywhere! Luckily, she found out that they vanish as soon as three or more of the same kind line up. Swap, match and wipe them out across 1,000 levels of this colorful match-3 puzzle game, before they spread all over the world.

FAIR PLAY, NO STRINGS ATTACHED
• The whole game is yours: nothing to buy, no premium levels, no paywalls.
• No ads, no tracking, no data collected, no sign-up.
• Works completely offline, perfect for your commute or a flight.
• No lives and no waiting: try a level again as often as you like. Your progress is never lost.

HOW TO PLAY
• Swap two neighboring monsters to line up three or more of the same kind.
• Every level gives you a limited number of moves and one or two lab tasks: collect monsters of a color, wipe off all the slime, crack the eggs or reach a score.
• Win with moves to spare and they turn into a bonus round for extra points.

POWER-UPS AND COMBOS
• Four in a row: a glowing monster that clears its whole row or column.
• L or T shape: a battery. Tap or swap it to blast everything around it.
• Five in a row: a syringe. Swap it with a monster to wipe out every monster of that color.
• Swap two power-ups together for bigger clears: two glowing monsters fire a row and a column, two batteries blast a giant cross, and two syringes clear the entire board!

A LAB FULL OF SURPRISES
• Boards in all kinds of shapes, with gaps the monsters fall right past.
• Slime: match monsters on the goo to wipe it off. Thick slime needs two wipes.
• Quarantine bubbles: a monster in a bubble can't be moved. Match it or hit it with a power-up to pop the bubble.
• Monster eggs: they block the board and hold up the monsters above. Make matches right next to them or hit them with power-ups until they crack open.
• Dr. Jo explains every new surprise the first time you meet it.

1,000 LEVELS, THREE DIFFICULTY MODES
• 1,000 levels on a winding level map, each one tested in hundreds of simulated games and tuned to a smooth difficulty curve: a gentle start, a steady climb, and an easier level after each tough one.
• Relaxed, Normal or Tough: pick the difficulty that suits you on the level map and switch whenever you like. Your stars stay yours.
• Earn up to 3 stars per level. The star meter shows how close you are to the next star, and you can replay any level you've won to beat your best.
• Every level starts from the same board on every device.
• Beyond level 1,000, the map keeps going with earlier layouts in new colors.

PLAY YOUR WAY
• Short levels, great for a quick break.
• A relaxing, almost meditative soundtrack composed especially for Monster Wipe, with sound effects mostly made just for the game too.
• Music, sound effects and vibration: switch each off with a single tap.
• Your progress is saved right on your device.
