IS7 Dragon Legend: Koi Free Spins & Bonus Roulette
Dragon Legend uses koi pairings and a separate bonus roulette feature. Knowing which symbols triggered the feature helps explain what the next screen is counting.

The dragon-themed reel game
Dragon Legend is a PG SOFT slot with five reels, three rows and nine paylines. IS7’s game collection includes its dragon artwork. Its feature structure revolves around koi pairings and a separate bonus roulette event.
The word Dragon appears in several titles we cover. This game does not compare two dealt cards like Dragon Tiger, and it does not use Dragon Tiger Luck’s selectable top and bottom reel groups.
Koi pairings and free spins
Koi pairings trigger free spins. The Koi Pair free-spin feature awards doubled line wins, so the feature’s multiplier needs to be read with the qualifying line result.
For example, if an eligible line win is 3 units before this doubling, it becomes 6 units. The condition refers to line wins within the feature; it should not be extended to every unrelated award or to a number shown elsewhere in the interface.
The bonus roulette trigger
Three Bonus symbols on reels two, three and four trigger the bonus roulette feature. This is a different trigger from the koi pairing. The specified reel positions matter when checking whether the symbols qualify.
Read the feature name when the screen changes. A bonus roulette result belongs to that feature’s rules, rather than to the doubled-line-win rule used in Koi Pair free spins.
A quick result checklist
- Identify whether the round triggered koi free spins or bonus roulette.
- For a line result, follow the highlighted path through the nine-payline layout.
- Check whether the Koi Pair doubling rule applies to that line win.
- For bonus roulette, wait for the feature award to settle before checking the total.
Is the roulette feature a separate roulette table?
It is a feature within Dragon Legend. The name alone does not establish the full betting options, number layout or rules of a separate roulette game. Use the instructions on the feature screen to understand how its prize is selected.
Which Dragon game guide should I use?
For two-card comparisons, choose Dragon Tiger. For selectable reel groups and a double-win multiplier, choose Dragon Tiger Luck. This page is for Dragon Legend’s koi and bonus-roulette features. The full title is the most useful starting point.
