Snowball
Snowball is a shooting game, developed and published by Tec Toy, only in Brazil. It was released as a built-in game on official Sega Master System clones released in the country starting from 2007.
In this game, the player must shoot snowballs towards cyclops monsters. The monsters can appear in one of the nine windows available in the screen. The snowballs can be shoot with ① (Ⓑ on the Mega Drive Control Pad) and the snowball itself must make contact with the monster, right or next to their eye. There is a time limit and a number of monsters to be hit for each stage. If the player manages to miss five monsters in the same round, it is Game Over.
