We're all way out in the Wild West in this game. It's a scorching hot desert scene with scattered cactus behind those wheels covered with images of a fine looking lady and just the kind of purse she might carry filled with fancy jewelery. There's also the very jovial-looking ticket collector, a steam engine and of course, the star attraction - an extremely colorful caboose.

Loose Caboose is a 25-pay line, 5-reel video slot game with a top jackpot of 5000x your line bet, paid out when you get 5 ENGINEERS on an active pay line. The engineer is also WILD and substitutes for all other symbols except the scattered CABOOSE. All symbols pay left to right except the scattered caboose which pays any and for which wins are multiplied by the total bet. 3 or more Scattered CABOOSES will trigger the Cash Train Feature - in this, the Cash Train appears and moves across the top row of symbols on the reels, revealing prizes such as free spins, additional multipliers, and bonus symbols. During free spins, any GOLD BONUS SYMBOLS will act as additional engineer symbols. If 3 or more cabooses appear during a free game, a further 5 free spins will be added to the current feature. There's a progressive jackpot that can be triggered at any point, limited to 1.5% total return to the player.

Loose Caboose is a good bit of fun, and with the added attraction of the progressive jackpot, it's gotta be worth some attention. The engineer and caboose both show great animations with accompanying sound effects when they appear on winning lines, providing extra visual appeal and giving the game the extra edge to help keep the player engaged.
