Cards Math

Excellent game

     

I really enjoy playing this game - it really requires some excercising of the grey matter. I prefer using playing cards (as opposed to just number plates) since you have to decode their value to continue. My primary suggestion would be to PLEASE make the font larger. My eyes aren't what they used to be and the buttons, especially the math function buttons, are too small with a great deal of room around them. The font could easily be doubled without changing the UI layout at all. Another thought: allow for different numbers (other than 24) to be solved - either as a setting at the beginning of play e.g.: solve the cards for 18, or randomize the number that must be solved for on each hand and display it in the upper right corner (or somewhere convenient). Also allow a pause where it will save the game in case you have to step away while playing - it would be mice to come back where I left off. Lastly, when the timer runs out, allow the player to see the solution of the final puzzle.
You could also enhance it for multiple players (on 1 machine or over Bluetooth) where the players get the same puzzles and the goal would be to answer the most puzzles without entering incorrect answers.
