Hey Arnold slots

One of the four high-resolution machines released in 1996.
Note that the high-resolution (and possibly low-resolution) machines can display a message about an upcoming event at the venue you are visiting.

Year released: 1996 (of course!)
Resolution and colour depth: 640x480 8bpp (may be 16bpp or 24bpp)
Lines playable (user-selectable): 1 (Red), 5, 10, 15, 20 (Black)
Credits per line (user-selectable): 1 (Heart), 5 (Diamond), 10 (Club), 20 (Spade) - on some, you can also bet 2 or 3 credits per line.
Gamble feature: Yes (Win x4 if correct for Suits, 1x for correct Red or Black - up to 5 consecutive wins)
Free games: Yes (15 triggered when 3-5 baseball bats are displayed. All wins are tripled, and additional free games can be won)

Should there be a Jungle Movie edition too? If so, I like some suggestions on symbols to use.
