Map

The map is what determines the size of the playable field in Starblast along with the pattern/manner in which asteroids are placed. There are currently 10000 maps available to be chosen from, ranging from 0000 to 9999. For each map, there are 19 available sizes ranging from "Micro" to "Huge". Maps are slightly different for team mode by there being a clear ring around the center of the map for the space stations. As of the 11-13-2019 update sparse maps generate far less often.

Tips
For Dueling one of the best maps is 4990. This map is an excellent map for dueling as there is a distinct area to mine and get ready for duels and an area to setup a duel and get started with no asteroids blocking you from having a great duel.
