Should You Play Tropical Thunder Slot for Real Money?

This is a simple game that doesn't immediately open up its possibilities. You can spin the reels indefinitely, getting paltry payouts for combinations of identical symbols and slightly higher payouts for the collector symbol. And wait for the Hold and Win bonus feature to start. And sadly watch the steady melting of the bankroll. But I advise you to try and still wait for the bonus game, which will definitely bring a big score and a lot of positive emotions.
