In Paradoxion, the objective of each level is to clear the playing board, which has been filled with different kinds of elements, like orbs and gems. To do so, the player has to use the contents of his inventory and produce certain combinations of elements. Whenever elements are eliminated, they cause an explosion, shifting other elements on the board. This can lead to chain reactions of combinations.
At the start, only simple elements are available, but later in the game, advanced items, like disintegrators (eliminate a whole row) or teleports (swap elements on the board) can be used.
The game provides 90 levels and a level editor which makes it possible to create and share new ones.
