You are a mole and a parent. Your babies are trapped in pens on the top of buildings. You need to rescue them before the level timer expires.
Heads pop out of the floor at random intervals. Whack blue heads to move the floor up. Whack red heads to move the floor down. When you reach the top of the building, whack the pen twice to free your baby. Some levels have two babies to save.
When your babies are released, they help you move the floor back down by whacking red heads.
Be careful. If you fall off the floor, you lose and have to start the level over. Your babies can fall off the floor too, but you are not penalized for this.
The game has nine levels. The first three levels are training levels where you rescue your babies and get used to the game. The next three levels introduce obstacles to make the process harder. The last three levels introduce even more obstacles.
The game has three levels of difficulty. They are Easy, Middle, and Hard. You gain XP for every head you whack. You gain XP for every baby you save. If you complete the levels objective, you gain even more XP. The harder the level, the more XP you achieve.
A leaderboard exists for each level of difficulty. Compare your XP scores with other players to see where you stand in each leaderboard.
The Settings option has Inventory. Here you can change your helmet color and skin color. Also, as you gain XP, you gain access to more mallets and helmets with lanterns. XP is organized by Level of Difficulty. Therefore, you need to achieve XP in each level to obtain better mallets and helmets with lanterns. In other words, you cannot achieve XP in the Easy level, and use it to obtain a better mallet in the Hard level. Your XP score is unique in each Level of Difficulty
Have fun!
