Description: Williams Jackpot Party Dotmations Slot Machine, WMS, 1998. Jackpot Party slot machine has a 192x64 dot matrix display (DMD) in addition to the three spinning reels. This was a very popular theme, as Williams recycled the Jackpot Party name into Jackpot Beach Party (purple glass) and Jackpot Country Party (brown glass), which use the same program ROMs, but different sound ROMs and different dotmatrix ROMs. When a party blower appears in all three reel windows, the slot machine goes to a bonus game, which is a matrix of boxes. An animated hand moves across the boxes, and the patron must press the Spin button to reveal what's behind any box (which reveals a bonus number of coins). If "poop" appears behind a box, the bonus game is over. This popular theme also morphed into the model 550 video slot machines. Available in a 5 coin model. Also the game came in two different color glasses (green/aqua and blue).

A multiline slot with a feature theme of going to a party. By collecting three party favors anywhere in the pay window, the player enters a second party bonus round. The party consists of choosing titles in a grid on the dotmation display board to win coins. The party continues until a title hiding a party pooper is chosen (screen says "poop"). As a special feature, the player will get an extra "Surprise Party" from a certain losing combination. The coins values behind the tiles range between 1 to 20 for a 1 coin bet. For multiple coin bets, the coin values behind the titles are multiplied by the coins bet (i.e. tile values range from 5 to 100 for a 5 coin bet). Also available in Jackpot Beach Party and Jackpot Country Party. The reel strips are the same for Jackpot Beach, Jackpot Country and Jackpot Party, only the top glass is different for the three games (JP Party is aqua, JP Beach is purple, JP Country is brown). They all use the same reel glass with a small party pooper noise maker just above the reels. The XU2/XU3 processor software is the same as Jackpot Party too (DMD and sound files are different for the three games though).
