Arcade game Lady Bug challenges players to control a ladybug navigating through mazes filled with food pellets "x"'s. The game features rotating doors that can trap enemies and aid in escape, while enemy hives in the center of each maze spawn out creatures at regular intervals. As levels progress, timers for the border increase, resulting in faster-spawning enemies.
Gameplay involves collecting X's, as well as power-ups like Poison, Letters, and Hearts. Power-ups have different effects: Poison is deadly to both player and enemy, while Letters add bonus points when collected at the right time. Hearts act as multipliers for X's, increasing their value by 2x, then 3x, and finally 5x. The player can also collect letters during a colored flash cycle to add them to the corresponding word, with "SPECIAL" granting an extra life and "EXTRA" unlocking a bonus round.
