Vast obelisks, existing beyond time and space, are believed to represent the very essence of purity and chaos. Unknown powers endlessly summon, shift, and banish these obelisks, igniting massive rifts between dimensions. Through these rifts, Mensors have learned to channel their powers to manipulate this phenomenon. They have come to call this eternal cycle... Obelus.

Obelus is a light-weight, 2-player abstract strategy game, playable in 10-15 minutes. Taking on the role of a powerful Mensor, you will summon obelisk shaped dice onto conflux cards, shift your obelisks according to the number showing, and banish your opponent’s obelisks. Through clever maneuvering, banished obelisks may be reformed, creating a rift that prevents further summoning on that conflux. You win when your opponent cannot legally summon or shift an obelisk!

Two game modes are included:
- Chaos: In this mode, dice are initially rolled into the center of the game area, adding a layer of emerging strategies in how players will make best use of the numbers rolled.
- Pure: This mode offers perfect information. Dice are never rolled, offering players full control over their chosen number as they are summoned and shifted around the game board.
