This is the first Bowling arcade video game and maybe even the first bowling video game ever. The only other bowling games released as early as 1977 are the RCA Studio II version, and Meadows Lanes (arcade, by Meadows Games) an almost exact copy of Robot Bowl. Apparently Meadow Games copied Exidy and not the contrary (though Meadows Lanes is even more crude graphically than Meadows Lanes).
To play the game (1 or 2 players), you have to move the bowler into position, bowl the ball fast or slow, and then hook the ball left or rigth.
In opposition to most other early Bowling games released later, you place your bowler where you want. Sadly this tend to make the game much too easy, strikes being fairly easy to achieve. Other games usually move automatically your bowler (or ball) continueously from left to right, challenging the player to throw the ball at the right moment.
