I made $30 deposit to Slots Jungle casino last weekend and cashed out $550. I could have cashed out $860, but I played it while waiting for my documents to be approved in order to make a cashout, lost $310 before I decided I need to stop, my balance kept going downhill, it didn't matter which slot game I played at that time. Games that won me big plays are Aztec Treasure Gurantee, Boyking Treasure, Loose Caboose. (see screen shots).
You have to be stubborn or patient with Loose Caboose game to anticipate for the bonus round with many free spins and wild symbols, at least that what I did. The name of the game says it all, it means the caboose getting loose, lol. You see two red caboose come out most often or you might get bonus round with only 3-4 spins, but usually you will get the bonus round later in a short time.
I had 4 free spins on my first bonus round of loose caboose which won me $4.50,, but I was stubborn, kept on playing until I had another bonus round with 8 free spins, two wild symbols, 3x multiplier which won me $79 and I kept on playing until I had the third bonus round with 10 free spins, two wild symbols and 4x multiplier which won me over $300 .
However, my stubborn sometimes was a killer, like today I had my account up to $200 at lucky club casino and I changed to play loose caboose, had two bonus rounds, but it took a while to get it and won too little each time, I ended up losing all my balance at Lucky Club casino. When I should leave the game will be a good question. I'll leave it when it takes too long to get to bonus round or it reaches a certain amount of my balance the next time I play this slot.
