how to determine the value of buying bonus game

Hi,
Many slot games offer a buy bonus feature, which comes with its own bet multiplier. every game has a different bet multiplier. For example, if you place a $10 bet and the bonus bet multiplier is 100x, you would need to spend $1,000 to buy the bonus game. I'm interested in finding out if anyone knows how to determine the bonus bet multiplier, such as 100x or 250x.


thanks,

I have not seen such high buy multipliers for online games. BTG games usually have a 60x to 100x buy cost. White Rabbit = 100x. Big Bucks Bandits Megaways = 60x.

The buy cost is based on the expected winnings of the bonus round. As a rule of thumb, the IGT bonus rounds paid about 60x the base bet. Golden Egypt and Scarab are IGT games where I expected to get 60x. I have not actually studies other games because the bonus is just part of the RTP. But I collected data on these bonus rounds because I needed the bonus value to model the game.

For the BTG games, the RTP is slightly better for buying the bonus versus playing the base game. For example, if BTG charges 60x for the bonus round, they might expect the bonus to pay 58 bets back. This makes the RTP 58/60 = 96.67%, whereas the base game RTP might be 96.00%.

Are you seeing Bonus Buy games in B&M casinos? One online site has a separate tab for Bonus Buy Games:
Peaky Blinders -- White Hat Studio
Thundering Gorilla -- Lightning Box
Moriarty Megaways -- IGT
Thundering Shenlong -- Lightning Box
Hot Hot Blazing Lock Fire Pots -- Light and Wonder
Ultimate Fire Link Olvera Street -- Light and Wonder
Monopoly Money Grab -- Light and Wonder
Reel 'Em In Tournament Fishing -- Light and Wonder
Ultimate Fire Link River Walk -- Light and Wonder
Wrigley's World -- Red Tiger
Big Bucks Bandits Megaways -- Reel-Play
Bison Valley -- IGT
Bankin' Bacon -- White Hat Studio
Big Catch Bass Fishing -- White Hat Studio
Bonanza Falls -- Big Time Gaming

Big Catch Bass Fishing is 100x. Base RTP 95.01% versus Bonus Buy RTP 95.05%. I have not played all of these games. I don't know whether any require more than 100x to buy a bonus game.

I used to play a lot of Bonus Buy games, but I have played almost zero in the last year because I had better options. I did play a Light and Wonder game at over $3000 per buy one time because I was in a leaderboard situation and this was the fastest way to get coin in. I got crushed on that play. I played another game at $1500 per spin for a jackpot party. I received jackpots on some games where I lost money.

Just to add to Mental's already complete reply: sometimes, in the game info, you can find the expected RTP when you use the "bonus buy" feature.

Divide the average bonus value by target RTP. If the average bonus is 50x wager and the target RTP is 90%, then 50/0.90 - 55.55, which you round down to 55x wager (90.9% RTP on buy a feature). The less the bonus costs, the lower the average win.

If you want to go the other way, check for info in the game rules. Just remember that the volatility is very high so the median feature amount will be much less than the average (left skew? I can never remember which one is which). If you spend 500x wager for a 97% RTP, the average will be 500*0.97, but you aint getting near that on the typical buy a feature. That average skewed by a very small number of 5000x wager and 10,000x base wager (regular spin) wins.

Some higher tier buy a features (guaranteed super mega feature with sticky multipliers and three wild reels per spin!) can go into hundreds of times wager amount. The people who are playing online slots with house money frequently purchase them.

I have not played any high variance buy-bonus games. I suppose they might exist. White Rabbit has a moderately valuable feature if your stack reach a height of 12, but the variance of a bonus feature is probably around 5. I think Bandits has a similar variance. Most base slot games have a variance of 20-40. So, the variance of bought bonuses is high when stated it dollars^2, but it is low in relation to the required bets units^2.

It may be useful for a well-bankrolled AP to know about these games. I don't think they are the most valuable tools in the toolbox. Recreational players might enjoy always being in a bonus round because bonus rounds often have play features that the base game does not offer.

I am not very familiar with the buy bonus games but in the old days when a slot gave you the choice of taking a fixed value payout or x number of spins it was almost always better to take the spins.

thanks everyone to reply .

I have two questions:
1. how to calculate the average bonus value ?

2. is it possible do it in this way=> 1/ probability of triggering bonus game?
e.g. if the probability of triggering the bonus game in the main game is 1/100, the value of the opportunity would be 1/0.01 = 100. Therefore, if you buy the bonus game directly without waiting to trigger it in the main game, you would need to pay 100x bet multiplier.

Thanks. I know there are many more of these games out there. I just ran across Tippy's Golden Pot™ with three buy levels.

Quote:

Buy Feature

This feature is available in base game only.

Activating this feature will instantly trigger the Bonus feature.

This feature is not available above a certain bet threshold.

The feature is played at the current bet.

Some settings and features may not be available in this game.

The Buy feature cost for 3, 4, 5 scattered Bonus symbols is 40x, 80x, 250x bet respectively.

There is no simple mathematical relationship between the probability of triggering in the main game and the value of the bonus. However, you can be sure that you will never receive a bonus worth 100 bets every 100 games. If this were true, the return to player would be 100% just from the bonus rounds.

The value of a bonus round is determined by the features the game designer put into the bonus round. This can be feature design done independently of any aspect of the base game.

Most PAR sheets will tell you the contribution of the bonus round to the payback percentage. The easiest way to find out is to ask someone who has the PAR sheets. When I was working in Gaming I had online access to almost all of the games PAR sheets.

I searched but can't find PAR sheets with the Buy bonus feature. Do you guys have any suggestions on this?

thanks,
