Bil Bolha

Bil Bolha (lit. Bil Bubble, supposed to be Bill Bubble) is a puzzle game developed by Devworks Game Technology and published by Tec Toy. It was released as a built-in game on several Sega Mega Drive models released in Brazil. AtGames also released an English version of this game as Mr. Balls, available as part of Arcade Motion Classic.

In this game, the player must help Bil Bolha and his brothers (which all of them shares the same appearance) to appear at the same time in a 5x5 board full of machines. Pressing any button in the Mega Drive Control Pad makes one relative of Bil to disappear, but other four "brothers" appears, each one in the adjacent sides from the former. The player can try to solve the puzzles in predefined boards or in a random formation of Bil and his brothers called "Sorteio" (lit. Shuffle).
