It's a turn based strategy game with a deckbuilding aspect. Except you use dices instead of cards.
Essentially you build a deck out of dices and each dice has a make-up of fields where the eyes usually are, like an attack field or a move field.
Some also have a monster side.
You throw dices and add the tokens you get to your token pool. So whenever a dice lands on "attack" you get an attack move added to your pool etc.
When a dice lands on a monster field, the dice "opens" into a grid of 6 fields like these which you can then place on the actual board.
The board starts out empty itself and has both players on it at opposite ends. Your goal is obviously to kill that opposing player. So when you throw a monster dice, you get to place such a 6 grid field and slowly build a way towards your opponent and he does the same.
Whenever you spawn such a field via monster side, you also get said monster on one of the 6 fields. That monster you can then move across the field via move tokens and use to attack other monsters via attack tokens.
Each monster also has unique properties in the form of Attack-power, defense-power and occasionally also special effects that activate under specific circumstances.
There's also other dices that instead of a monster side have other features like the ability to place a warp hole and such, but that'd go too much into details.
