Most players love stumbling upon a hidden feature on a fruit machine, and over the years there have been dozens of such features built into a range of different machines, however it is often the most basic ones that ensure you get a tad more excitement when playing.
Take for example the Bar X fruit machine, at the time of its launch that very low tech slot machine broke all records for fruit machine income, which to be honest was quite surprise for it one of the most basic fruit machine ever launched.
The Bar X slot offered players a simple three stepper reel type of playing structure, one single pay-line and when playing it the only reel symbols that could be spun in were X’s, 0’s and Bars. The X’s and Bars were the only reel symbols that could form a winning combination and you would need to spin in a set of three or those matching symbols to receive a winning payout.
Being fruit machine the you could also be awarded with the hold feature, that would allow you to hold any of the reels in place for the next spin and every now and then the Bar X fruit machine could award a set of three nudges to players too.
However, what did make this a slot worth playing was the fact it did have a couple of hidden featured built into it. As more and more players became aware of them and due to the popularity of the fruit machine it did become one of the best known hidden features!
When a player had been awarded a set of nudges, and was unable to spin in a matching set of three symbols the best strategy was to nudge in two matching X symbols or if possible two matching Bar symbols.
If before the next spin you play off the hold feature was offered directly after the nudge and you did nudge in two X or Bar symbols on the win-line then no symbols should be held, for by not holding any symbols you would be guaranteed of spinning in a winning combination on that next spin!
Also if you spun in via the base game two matching X or two matching Bar symbols and were offered the hold feature then the best way of playing this fruit machine was and still is to hold both of those matching symbols.
If on the next spin you are offered the hold feature again then once again you must hold both of those two matching symbols, if the hold feature is offered once again then you must hold those two symbols once again but this time you will be guaranteed of spinning in the third matching reel symbols required to form a winning combination!
Whilst there have been dozens of different variance of the Bar X fruit machine design and launched over the years it is the classic Electrocoin version that offers those two hidden features, and even though that fruit machine is decades old you will still find them in amusement arcades in the UK!
