Jackpot, a DOS-game from 1991 written by Tim de Groot. A game involving cards, a joker bar and bonus points. It's all based on luck and good timing.

You can download the game here. It will run in DOSBox but the timing is a little off. It runs perfectly on older XT and AT systems, though.

Instructions on playing the game:

Spacebar : roll new cards
Keys 1 to 4: 'hold' a card for the next roll. This can only be done if 'HOLD' is written under the cards.
F1 : Help (in Dutch)
F3 : Clear highscore list
F5 : End game
F9 : Show highscore list
S : Toggle sound on/off
D : Toggle demo play on/off.

The scoring of the cards is as following:

4 x DJAHIL cards	200 points
4 x 5 BAR cards	180 points
4 x 3 BAR cards	170 points
4 x 1 BAR cards	160 points
4 identical 'regular' cards	150 points
3 x DJAHIL cards	40 points
3 x 5 BAR cards	35 points
3 x 3 BAR cards	30 points
3 x 1 BAR cards	25 points
3 identical 'regular' cards	20 points
2 x DJAHIL cards	15 points
2 x 5 BAR cards	10 points
2 x 3 BAR cards	7 points
2 x 1 BAR cards	5 points
2 identical 'regular' cards on row	3 points
2 identical 'regular' cards	2 points

The bonus points will be collected over time and you can gamble them when you get a 'BONUS' card on a roll or when the bar is completely full.

On the bottom you'll see a playing cards row which can be used whenever you have a 'JOKER' card on a roll. The idea is to collect 21 points using the joker bar. If you have a 'JOKER' card and used it you'll often have the ability to hold the cards. To use the 'JOKER' again hold all four cards by pressing 1 to 4 and then roll again.
