When slot machines are developed symbols discrete distribution should be provided for the reels. It is not so complex problem, where RTP (return to player) is generally calculated. The RTP should be below 100% and usually it is higher than 90%.

There are many slot machine games available even on-line. My question is - what would be the best approach for slot strips reconstruction by observation of many games?

Some slot games manufacturing companies are interested to reproduce reels strips from their competitors. What would be the best approach for such reverse engineering?

My ideas at the moment are related to:

1. Screen capturing;

2. Image recognition;

3. Sequence reconstruction;

Steps 1 and 2 are not so complex, but step 3 is not so easy. Brute force for matching all possible combinations is not applicable.
