Weird Characters!
Meet various characters! If you feel like you’ve seen them somewhere before, just ignore it! Winning characters in the game can also give you some paid rewards! So collect a lot of characters!

Use your cards!
Collect cards or use the cards given away at the Dragon Store every day to make your game a success! Since cards are consumed, important cards can be recharged through batteries!

Mix Dice in various shapes!
In the game, you can bring two mix dice in addition to the basic dice. Mix dice have different shapes and numbers, and if you want, you can randomly change the numbers to make them more advantageous! Mix dice with changed numbers have an expiration date like cards, so they can be recharged through batteries!

Attack! Attack! Attack!
If you catch up with the opponent character in front of you, you can attack and stop for a moment! Additionally, the Lucky Dice can be activated, allowing you to use the dice once more! If you have good luck through mix dice, you can continuously catch your opponent!

Link your characters!
If your characters overlap, you can combine them through links! Linked characters are one body and can end the game with just one goal! However, be careful as the game can also explode with just one attack!

Only one winner!
There is only one winner in this game! Do whatever it takes to win!

Party with your friends!
You can play with your friends by making a party through the friend function.

More Rewards! Rumble Rank!
Rumble Rank starts at specific periods. The higher your rank, the more rewards you can get. Since Rumble Rank requires Silver Key, it’s better to play Rumble Rank than the general game!

Catch the bad guys! Wanted!
Capture the weekly wanted criminals and collect gold! You can buy card pieces with gold or buy more at the Dragon Store!
