A pure dice rolling two player game. To win the game, a player must be the first one to have all numbers from 1 to 10 either marked or locked. Two dice is used to hit the numbers. A turn, ie. rolling the dice, continues as long as results of both dice (individual results or their sum) can be used in actions.

The actions are:-
1 mark own unmarked number, or
2 unlock(mark) own locked number, or
3 unmark the other player's marked number

At the beginning of a turn, a player is supposed lock all his remaining marked numbers (that the other player has not managed to unmark on his turn). During a turn, a player has an option to unlock some of these numbers (depending on the dice results), but can decide to not do so.
