When the bonus symbol appear anywhere on the reels you will be rewarded with bonus points, which are accumulated while you play, so the same story as every slot of theirs, the higher the bet is, then the bonus round will be triggered more faster, the lower the bet is, you have long way till the bonus round is triggered. I must say I am not impressed with the bonus round, just because it doesn't pay much, actually ridiculous sum of money, no matter how much you deposit. While I have been playing this slot the maximum I got from that bonus round was 5 x the bet which is really low sum, with one word, the bonus round is not worth it, so you could chase it.
This game also offers free spins feature, which by the way I am a bit disappointed with that feature. The free spins will be triggered when 3 or more flags with scatter symbol on it, will appear anywhere on the reels. So getting 3 of them will reward you with only 5 free spins,4 of them 10 free spins and the maximum free spins you can get from this game is 25 free spins, triggering 5 flags symbols which I doubt ,just because the free spins are really hard to be triggered.
This 25 payline slot game from Bossmedia didn’t impressed me with anything, neither with the free spins, hard to catch and only few or 5 of them, the bonus round which you won’t make it till the end till 5th level, so with one conclusion, very bad graphics, low variance payout game, which offered as a free spins I will play it, but wont enjoy so much, knowing it won’t pay me much.
