I find myself in somehow disturbed when visiting some (big) online casinos and there is hundreds and hundreds of slot games.. presented just like that ..
This is not resembling in anyway the slot machines in a (real) casino !
I thinked of what if making an organisation like, for example making rooms for each game, with a limeted number of slots, say 10 for example. every (machine) identified apart, and every one with his own progressing jackpot,
So for example when entering the room you have to choose from the available (machines) to start playing !!
Yeah, those casinos bombards you with thousands of slot games. Each have their own rules, but they are the same with slight changes (like payout table depending on horizontal, vertical, diagonal match and so on). They have all these combination so that they can show you that you are "winning" through those multiple row/column after each roll (though you aren't) so you continue playing. If you are looking for very simple slot machine you can try the one at CryptoGames. No stupid rules. Middle horizontal lineup combination with easy to understand payout table
