A nice little game for gambling on the next dice roll and chasing high scores.
I enjoyed my pursuit of it.
The UI and color scheme could use a little more love, and if you could show the player (perhaps via animations) which combinations of dice (a 5, a 1, a pair, three of a kind, a straight, etc.) they rolled and how many points that earned them, then they would certainly save themselves a lot of time looking at the scoring rules and it would become self-explanatory.
Combine that with a leaderboard and the game is perfect.
And a soundtrack :)
Later power-ups, jokers, etc. can be implemented, but may not be necessary if the hunt for a better ranking is well implemented.
Please let me know if that's the direction the game is going in. Because then I'll get myself a top 10 ranking!
