In 243ways game,I tried to calculate every symbol as scatter, and got rtp = 95.2739377%.
However, the actual rtp is about 114%.

What can be my mistake?

Maybe provide some reel strips and your calculation for at least one of the symbols.

Also how do you know the answer is supposed to be 114%? Slot machines aren't usually programmed to return more money than they take in.

I try to use 3*5 reels, every reel contain 32 symbols, and I look on all the trios- for every symbol I count the trios it appears in.
For example: Symbol "1" found 2 times in the first reel, and there is one wild adjacent to one of the "1"s, so I count the 7 trios contain "1" or wild, and count 2 more for the trios that contain both.

for symbol "1":
Reel 1: 2 + 1 wild
Reel 2: 3 + 1 wild
Reel 3: 1 + 1 wild
Reel 4: 2 + 1 wild
Reel 5: 3 + 1 wild

so the probability to have five "1"s in a line is 9*12*6*9*12/32^5

Hi,

I've done a lot of 243 ways slots games. Our product brand is 1S Games / Gamingsoft

243 Lines is different from 243 Ways because if you get single 5-hit for 243 ways , you don't pay anymore 4hit and 3-hit.

You can privately message me at my email address

I reduced the superfluous 4 and 3 hits. But still I *underestimate* the actual rtp. It means there are some hits that I don't count probably.

This is correct. If you have mistakes, it is with 3 and 4 of a kind, because those depend on the layout of the reels.

In your case, for 4 of a kind, you probably calculated 9*12*6*9*20, but 20 is only correct if the symbol doesn't appear within 2 positions of the wild or itself.

Another issue is having wilds on the first reel. This is very problematic in multi way games. If 5 wilds appear, do you pay 5 of a kind for all of your symbols?

Again, how do you know the correct RTP that you are comparing to?
