For lowest variance option,
find a Blackjack Machine where you play 7 hands against the Dealer. The rules are decent overall (but waaay better than all the normal Caesars properties BJ machines, where you get e.g. no doubling or split whatsoever).
You can choose your own denominations on the machine, so you decide the time/variance trade off.
It's also just $10/tier versus the large multi-player BJ machines (which I think are $50/tier).
P.S.: Another way is sitting at a full Baccarat table game, and only betting when the floor is looking over. Low house edge and you get 'point-earning' time while not risking money...
If anyone ever hears about a new hotel tier credit promo, would be really thankful for them sharing it here...
