The sound of a train rolls by with every spin while Casey Jones is the free spins symbol and with 3 spun on the reels will trigger 10 free spins at a 2x multiplier. 4 Casey Jones symbols will trigger 20 free spins at a 3x multiplier and 5 will elicit the highest multiplier at 4x the win with a sum total of 40 free spins. The mighty train engine, (is it Casey Jone’s very own steam train, the Cannonball Express?) or is it just All Aboard slots expanding wild where all wins are multiplied by 2 when the train appears on reels 1 and 2? Yes, that's more like it. Talk about a cargo of multipliers and free spins plus a bonus bell that triggers a bonus round. 3 or more bells keeps both train lovers and those who could give a lick about trains enough motivation to climb on board. Choose from a lineup of cargo cars to reveal bonus points. The cargo cars are filled with chickens, pigs, sheep and other animals but once players have clicked on an empty cargo car, the bonus round ends.
