Which slots can the daily casino bonus be used on?

Which slots are the best to use the daily bonus on at AmericanLuck? I'm currently playing Joker from Hell by Evoplay, and I like it. However, I'm wondering if there are other slots where the bonus would be more effective. Do you have any favorites that you can recommend?

Oh, did you just register? I often use the daily bonus on Joker from Hellfire at AmericanLuck too. I especially like the bonus rounds. To test new mechanics, though, you can try any slot with medium volatility and use the casino daily bonus there. GC accumulates more steadily there, and SC can be tweaked a little in bonuses. Do you prefer playing for quick wins or for a series of accumulations? By the way, what is the registration bonus now? I heard that AmericanLuck has one of the best.
