Q: Based on the linked description of how slot machines work, how should you react to a winning streak? Consider a situation where you have won on three consecutive pulls, should you: Increase your bet Decrease your bet Neither increase nor decrease your bet ------------------------------------------------------------------------------------ Increase: Assuming that the slot machine is really selecting numbers randomly, and that this number is converted to a position on the virtual wheel that points to a position on the real reel, I would not increase or decrease my bet. However, if I was not certain that the electronic machine was operating like it is supposed to, I may alter my bet. That is, if I play 20 times and win each time, I would assume that either I am ridiculously lucky today (unlikely) or that the machine is damaged such that it is not acting in the random fashion it was designed to act in. For instance, in a mechanical machine, the notches may have been worn down enough such that certain symbols never appear and others appear over and over again in each reel. Consequently, I might increase my bet, hoping that the machine really is broken and will once again act non-randomly (such that certain outcomes are more likely to occur than they should be given the machine specifications) and win me more money. Decrease: It would be logical to reduce the bet, or stop playing. Although it is statistically equal that one could win when considered independently, the probability that one woud win given three previous consecutive wins is extremely low. Neither: I think would keep the amount of my bet constant because although it may seem that 'winning streak' may be a rare event, each pull at the slot machine yields independent probability of jackpot. So, you always have a same chance at gaining money- keep it steady.
