Slot machine strategies were most prevalent with older machines that used mechanical reels to display and determine results, and the standard three wheel slots were limited in the size of payouts they could offer because there were only 1,000 possible combinations. Over-time, with more reliable machines being developed, the range of symbols on each reel may be increased, thus decreasing the probability of the jackpot being won. It wasn't until the 1980s, on the contrary, that manufacturers incorporated electronics into their machines and certain symbols might be weighted thus altering the true randomness of the rtp slot online machine. Video slots machines have no moving parts and allow for a more interactive element to be introduced such as advanced graphics and bonus games. The increase from 3 to 5 reels also means that the odds rocket to 300 million to 1 against - making the huge jackpots you see on some progressive slots possible. The notion of having the capacity to bet on multiple lines also came about at this time and players could bet on as many as twenty lines in one spin. To offset the feeling that the players money didn't last long, the bonus games were devised to keep players hooked for longer. The payouts on slot machines vary greatly, which is one area that players should consider when choosing which machine to play. Some pay out only 80% whereas other go all the way to 98% so one of the primary strategic decisions to make begins is simply this - look-at the payout rates.
