Experiment
Some levels may seem impossible, with a maze of obstacles making it difficult to even imagine hitting the target. But don't give up. There's always a solution. Be willing to experiment and try every possible shot. You may not realize how some obstacles and items will react until they're actually hit with a ragdoll. And the ultimate goal is to clear the level, not necessarily to preserve ragdolls. So take as many shots as needed to experiment and find a solution.
Menu
If you've successfully completed a level but feel you could achieve a better score, you can replay the level by simply returning to the menu screen during game play and selecting the same level again. Also, if you encounter a level that you can't seem to beat, you can use the same menu trick to skip ahead to any of the upcoming four levels.
Level 50
Titled "Da Vinci Dreams," Level 50 poses a tricky challenge, with the three interlocked wheels located in the bottom right portion of the screen that spin like the gears of a clock. The target spins around these wheels. To make matters worse, barricades protect the wheels, providing only a small window to shoot through. At the start, fire a steady stream of ragdolls into the top wheel's piston arm to reverse the wheels, bringing the target spinning towards you and the open window. Time your shot through the window to strike the target.
Level 99
Called the "Trash Compactor," Level 99 features walls closing in on you, You can clear the level on five shots if you shoot the four levers controlling the walls and then the target. But for a one-shot victory, aim a ragdoll at the "C" in "Compactor," cutting it as close as possible as the walls close in. The ragdoll should bounce off and land on top of the target to clear the level.
Level 100
Level 100, "Equilibrium," places the cannon on the right with the target in a bunch of marbles on the left. A plank falls into place and obstructs most of the marbles. Try to shoot a ragdoll just before the opening on the left of the plank. This may dislodge a stuck marble, triggering a cascade that carries the target into the ragdoll.
