This is a new old stock game, strade stimulator 5 cent game. After inserting the coin the balls drop to the bottom of the playfield. Then they are shot up to the top one by one. Next the top button is pushed and bets are placed on the order that the balls will finish the race. Very fun to play over and over. Even though it is new old stock, all the metal parts needed to be gone over. So it was completely dissasembled and cleaned. Now it works like new and looks like new. Includes a pad of the original betting slips that were used and the original instruction sheet and payout odds sheet.
