I believe in giving them the action they require, and then giving them more action. The casino wants us to play the deposit once, and the bonus once. We want to chose the right game to play to get through this action that gives the house the smallest edge, and that game will always be Blackjack. This doesn't mean that I don't play slots, this means I may play slots with my possible winnings. If you are a slot player, then playing an online casino gives you many more chances at winning a very large jackpot than playing at a brick and mortar casino.
Slots also provide the casino with the biggest edge.
I like to play until I lose half the bonus, or double it. I have locked in a win either way, so this allows me to have fun while I play. This does not always happen, and this is where Oscar comes in. Oscar starts with a one unit bet. We bet one unit and win.
