Lady Bug is an insect-themed maze chase arcade game produced by Universal Games and released in 1981. Its gameplay was inspired by Pac-Man but with several additions to the formula, such as the ability to alter the layout of the maze through gate-shifting. The goal of Lady Bug is to eat all "flowers", hearts and letters in the maze while avoiding other insects. The player is represented by a red, yellow, and green character resembling a ladybug while the enemy insects' appearance varies by level. The border of the maze acts as timer, with each circuit signaling the release of an enemy insect from the central area, up to (generally) a maximum of four. The speed of the circuit increases on stages 2 and 5. Unlike the more famous Pac-Man, the player can alter the layout of the maze by shifting any of the twenty green gates. It is not possible to completely isolate a portion of the maze through gate-shifting. When the fourth enemy insect enters the maze, the central area will show a level-specific vegetable.

The randomly placed skull icons are lethal to ladybugs and enemy insects. An enemy insect who dies returns to the central area. Once a vegetable is eaten, the central area will remain empty unless an enemy insect dies and is re-released, revealing a new vegetable.

If a heart is consumed while it is blue, a point multiplier will come into effect, indicated by the blue section in the upper right corner of the screen. The first blue heart doubles all point values, the second triples them and the third quintuples them. This multiplier lasts until the level is complete. Eating hearts while they are yellow or red offers no benefit beyond the points collected. At each level, the maze will contain three...
