The Wild symbol has a payout of 10,000x the line bet, or 500x total bet, for getting 5 of them. The Scatters pay a lower 100x total bet, but is still acceptable, whilst the other symbols pay from 62.5x down to 5x total bet for any 5 of each kind. No new game can provide such a paytable nowadays! Not only that, getting 2 Scatters would pay 2x total bet, and getting 3 or more would trigger 12 free spins with a 3x multiplier. That's slightly below the good standard of 15 free spins with a 3x multiplier, but the possible retriggers may improve on the wins significantly.
Getting the Girl Bonus symbol on both reels 1 and 5 would trigger a 'Pick And Win' feature, something that I have never liked so far, but in this game, this feature could actually pay up to 100x the total bet amount, so that's something worthwhile to chase and to get! Nonetheless, I have yet to get such a win! My wins have all been below 30x my bet amount, but for a bonus game, those too are quite acceptable. Luckier players may well get much bigger wins, both from the Free Spins and the Pick And Win bonus games.
Anyway, sad to say, my luck on Bangkok Nights have never been good, but then again, none of NextGen's games have ever been any good to me either. This is purely individualistic of course, and luck is never the same with another player. Nonetheless, this is one game worth playing.
