These generally don't get mentioned here, I would assume because of the (almost) complete lack of skill involved. For those of you who have never played one, they generally set the machines to a mode in which every spin wins something or, at the very least, does not lose anything. They then set a timer, usually something like 5 minutes, and start the round. At the end of the allotted time the top scores advance and/or receive prizes. I said "(almost) complete lack of skill" above because the one "skill" involved is to minimize the amount of time that the reels aren't spinning. One extra spin during the round can make a difference in your finishing position. Many folks take the approach of hammering away on the "play" button, which results in quite a frenzy in the tournament area. The reason I bring this up is that, despite the lack of any mental stimulation, these tournaments can be a decent +EV opportunity under the right conditions. I just came back from vacation at a casino resort that had a daily slot tournament which was free to enter. The tournament area had 20 machines and you could enter one 5 minute session each day. The first session was at 9am and was frequently ill-attended (there were only 12 players on one particular day). The prizes were awarded as free slot play. First prize in each session was $100 USD, second was $50, third was $25 and everyone else got $10. So for a full session, the expected value was $17.25 in free slot play which became as much as $22.08 with only 12 players. That may not sound like much, but I challenge you to find another opportunity for that much EV in 5 minutes elsewhere in the casino, without risking a substantial bet! Add it up for each day you are there and you have an expected $124.25 to $154.56 giveaway for a one week stay. Now you're saying, "but it's free slot play and not worth the full value". This is true, but if you play through it once on a low denomination machine (in order to maximize the number of spins/plays), your result should be within a reasonable range of the machine's programmed payout rate. There will of course be some variance, which will decrease as the number of spins/plays increases. In my case, I played 4 times and was lucky enough to finish 1st, 2nd, 6th and 3rd. My free play session results were $100 -> $105, $50 -> $30, $10 -> $18, $25 -> $20. I ended up with $173 from $185 in free play in exchange for 20 minutes of my time without any risk at all. Compare that to the ~$1,000 I netted from the rest of my casino activity over approximately 9 hours of play while risking my own money. I just got a mailer about a slot tournament at a local casino. The prize pool is $40,000 CAD for an entry fee of $200 with only 115 seats. The top prize is $20,000 and the top 20 participants will finish in the money. Hopefully you see what I see, which is the $17,000 overlay. Just by pure luck alone, this event has a better EV ($147.83 or 74% of the entry fee) than any blackjack tournament I have ever played, even after factoring in my own skill level vs the skill level of the field. With only 115 participants I also have roughly the same odds of winning the grand prize as I have estimated for those same blackjack tournaments and a better chance of finishing in the money. My point is that, while we love the mental stimulation and challenge of tournament play, don't rule out other opportunities which may offer better EV, or a free roll. Over time, these can add significantly to your bankroll.
