We're sorry to hear about the recent runs of bad luck. At 4ThePlayer, we are committed to being transparent and engaging with our players about the chances in our games and we provide more stats on our games than any other supplier (that we know of). We provide the following statistics in our help files for all our games (the following are from 123 BOOM!):
Bonus Frequency: 1 in 203 spins
Average best win after 100 spins:
All players - 40x bet
1 in 10 players - 165x bet
1 in 100 players - 409x bet
1 in 1000 players - 810x bet
This can be read as follows: if 10 players all played 100 spins and logged their best win over those 100 spins, then statistically we'd expect the average best win of all 10 players to be 40x bet. 1 of the 10 players we'd expect to get a 165x bet best win (again, statistically speaking).
To give you some context over your bad runs of luck:
Over 500 spins, we'd expect the average best win for all players to be 115x. We'd expect from 1076 players that only 1 player would not hit 10x or above over 500 spins, so you definitely had a very bad run of luck.
Regards the bonus, the average payout for a bonus spin is 60x bet. Over 40 bonus triggers, the chance of getting only 1 bonus win of 80x or over is 1 in 2188; that is, from 2188 players we'd expect 2187 would all get more than 1 bonus over 80x. The luckiest player out of those 2188 players could expect to get a 2203x bet bonus spin.
We hope that the above highlights how unlucky you both were. We also appreciate that all games do not appeal to all players; this game is a medium-high volatility game with a bonus frequency of 1 in 203 spins. If you would like bigger wins in the base game, you can try 9k Yeti, which is our highest volatility game. If you would like bigger bonus wins, 2 Gods Zeus Vs Thor has a 67x bet average bonus win with a bonus hit frequency of 1 in 185 spins.
Finally, we are always interested in feedback on maths models! We are developing a maths beta program for upcoming games, where we are inviting players to feed back on our latest maths models. If you are interested in helping us with this, then please feel free to send us a private message.
