Different Wario Lands
The Wario Land series can be split in three groups.

Wario Land: Super Mario Land 3 and Virtual Boy Wario Land
The first two Wario Lands bear more similarities to Super Mario Bros. than do subsequent Wario Lands. These Wario Lands have floating blocks much like ? Blocks that contain coins, helmets, or hearts (collect 100 for a 1-up). Helmets give Wario new abilities, such as the ability to fly or pound the ground. If Wario touches an enemy, he will take damage, lose his helmets, or shrink down in size. Levels have a time limit.

Wario Land II and Wario Land 3
Floating blocks are gone, as are level time limits. Wario is immortal and can't lose lives (since there are none), but touching an enemy stuns Wario, knocking him backward. Some enemies don't stun Wario but transform him in one of several ways, these transformations replacing the helmets of the first two games. For example, if Wario touches a zombie, he will become a zombie, or if he is crushed by something heavy, he will be flattened. Wario's transformations can help him complete the level. Puffy Wario, for example, can float through the air, providing access to areas previously out of reach.

Wario Land 4 and Wario Land: Shake It!
Wario is no longer immortal but instead has Heart Points. If Wario touches an enemy, he will lose a heart. If all hearts are gone, Wario is kicked out of the level, and he loses everything he collects in the level up to that point. However, Wario can't get a game over. Wario's transformations are still in the games, but they serve more minor roles. Levels are still without time limits, though one commences after activating a Frog Switch (in Wario Land 4) or shaking a Merfle Barrel (in Wario Land: Shake It!). If Wario returns to the start of the level in time, the level is cleared. In Wario Land 4, if the timer reaches zero, Wario loses the coins he has collected until none remain. When Wario has no coins left, he is sent back to the Golden Pyramid. In Wario Land: Shake it! if the timer reaches zero, Wario loses all of his coins and collected items. However, If Wario has reached a checkpoint, he is sent back to it.
