Every game is better when you are winning. One thing is assured that you can't beat the house edge, so you are now winning for your good luck only, sooner or later the sakes with red will follow. If only then you can control yourself then you will be the winner whether its a slot or a dice.
Yup Even chess would make it very fun for you if you are winning. I don't see slots to be better than dice though, there are more options there than dice which only has two ways to go if you just stick to 50. There are however enjoyable games than dice and slot which OP should just be playing like poker or blackjack. But maybe he has strategies in slot that he enjoyed it than any games.
Whatever the game, winning always makes people happy. This is the truth, with dice and slot even the person without skills will win if he/she has got luck. Strategies too won't be effective all the time, which means there is need for large backing to try each and every strategy.
