There are a total of 17 hand combinations that will appear on the board in Eiffel Tower poker. It can be complicated so you need to pay close attention. You must also be aware of all the board cards in order to help you in assessing the likely winning hands. How coordinated the board cards are will dictate what is the likely winner will be. As an example, if the bottom row contains all high cards (eg. JQK) or all low (eg. 246) and the cards in 2 of the other 3 rows come out the opposite any possibility of a straight is gone. A similar scenario exists for flush cards.
Subject to the cautions above board cards with straight possibilities are fairly common, while flush possibilities are less so. A qualifying set of trips appearing on the board is a big longshot, but it bears mentioning this. If you hold a pair of aces in your hand you have a good full house but it may not be enough. With 8 players there are a total of 28 cards held by the other 7 players so there is a good possibility (about 68%) that one of them has the case card in their hand. Additionally, if there is even 1 other card on the board that is of a rank higher than the trips a bigger full house is possible. When the board is not coordinated and no qualifying pair appears the winning hand is usually trips.
While Eiffel Tower poker should be considered a variation of Omaha there is an important difference to consider. The difference is in how the board cards are revealed. Omaha highlow is a great game for a loose, low stakes home poker game. With 4 hole cards and only one betting round before seeing the 3 cards that make up the flop most players will stay in with almost anything to see what happens. With a miracle flop you could end up with anything from trips, a straight, flush, full house, quads or even a royal flush. Even without such miracles you might have a good drawing hand with 4 to a straight or flush.
Now compare Eiffel Tower to Omaha. Yes, after the first betting round you see 3 cards from the bottom row. But, you can only use one of those cards. The very best hand that anyone can have at this point is a set. Just a single pair is the second best hand. Should you be fortunate enough to get a set the next row could give you quads (22.5:1 or about 4%) but any other improvement is still at least a 2 card draw away. You may have to go through up to 3 additional rounds of betting to find out if you make that draw. For this reason routinely seeing the flop with any random 4 cards in your hand is not a good strategy.
