Right the game was created on pieces of paper as a first copy. From here the initial testing stage can commence. After playing a few games of 'Juke' some amendments to the rules and alteration to the gameplay were discussed. Here are the changes and why...

After winning 'Juke' in one round a player with a low score can easily be out of the rest of the game with the other player calling Juke (with the bonus of the triple points score) so a winning Juke score will be doubled from now on.
With this a player who loses a couple of rounds can still be in the game without being too far behind, keeping the game close.

Symbols, letters and numbers could be placed on the border of the card?
When holding the cards players may be aware of showing cards when holding them - when the symbols were in the middle. If placed on the border the cards can be held more closely.

Possibly use the symbols more E.G four of a kind may be double the final score and five of a kind could be triple score for that round.
Players can chose not to go for duke and try and attain symbols for a higher score. The game will be higher scores (which to the player will feel more of an accomplishment).

Reducing the amount of cards - especially the lowest and highest numbers. Maybe six low and four high.
More numbers ranging between 3 and 6 will surface which will then attend a more close game. As before alot of 1's came into hand which was slightly annoying.!.
