Called "Liberty Bell", this slot machine game is recognized as the very first American slot machine, the prototype for today's slots, with its basic, dependable layout. In actual fact, its timeless design and craftsmanship is still being used in the mechanical gaming devices today. Who guessed that 2 simple reels bearing 20 symbols would spark a real trend and gather such a following! The original Liberty Bell, true to its name, had a bell that rang loudly whenever a player was lucky enough to hit a winning combo. While Mills had the bell removed, it was subsequently brought back in modern-day slot machines. Due to the Liberty Bell's wide success, it underwent adjustments as time marched on, to keep it current.
