NEW 3-Reel Mechanical Flintstones slot machine! I got the Flintstones Family free spins bonus feature. This is a $3.00 bet with Extra Dino enabled to give you added chances at waking up Dino for those extra bonus symbol hats & win multipliers. Fun game. For me, I felt like the bonuses were coming out more often then they typically do on the 3RM Wonka or WOZ Road to Emerald City (then again, im paying a little extra for Dino LOL). Harrahs, AC.
