Dragon Duo is a slot game by Red Tiger Gaming built around Ice and Fire Tokens, dragon-triggered effects and a free spins feature. Symbols landing on the middle three reels can show Ice Tokens, Fire Tokens, or both, with each token linked to a different mechanic during the spin.
The Ice Dragon may activate at the start of a spin and add a multiplier for each Ice Token that lands. Fire Tokens can turn symbols into Wilds if a win is formed after the transformation. After the reels stop, Ice Breath may convert matching symbols on the first reel, while Fire Breath can trigger a respin with royal symbols removed and Wilds held in place. Players can use the demo version to play for free and practice before playing for real money.
Free Spins are awarded with symbols on reels 1 and 5, starting 10 spins and adding 10 more if the feature is retriggered. This can upgrade the bonus to Super Free Spins, where both dragons activate on every spin. A feature buy option is also listed for the bonus rounds.
