Flash Duel is a simple, fast card game that simulates sparring matches amongst Fantasy Strike characters. It's all about getting to the right position on the board while managing your hand. There's a bluffing aspect as well. Scoring a single hit wins the round, and even playing best 3 out of 5 rounds is super fast.

Seven Modes of Play:
1. Simple mode, for first time players
2. Full mode, using the character abilities
3. Custom Clockwork: build your own character!
4. 2v2 team battle
5. Solo play, with 10 achievements to earn
6. Raid on Deathstrike Dragon: 2, 3, or 4 players cooperate against a powerful 5th player controlling the Dragon
7. Betrayal at Raid on Deathstrike Dragon: A more difficult raid where one player is secretly on the Dragon's side!

There are 20 characters to choose from, each with their own special abilities, allowing for hundreds of different matchups across all the game modes. There's also a very special 21st character, Deathstrike Dragon, who is so powerful that it takes multiple mortals to team up against him.
