Players are wizards competing against one another for the title of Master of Wizards. Spells can be cast to summon creatures to fight or to create new terrain features. Creatures can also destroy opposing terrain markers.
As a wizard's terrain encircles more and more flux globes, his ability to cast spells increases.
After 10 turns, the wizards with the most Flux in his domain is declared the winner.
Flux is a very simple game, maybe 3 pages of rules. Creatures have a combat strength and movement value. To fight just roll a die and add your combat strength. High total wins. Spell casting is equally simple, just based on the range of the spell instead.
Flux is a nice, no-brainer way to end an evening.
