Portable rummikub game

Hello!
Here i present to you my design of a pocket able rummikub version.
This idea was born out of my intrest in the EDC world, having tons of useful and fun portable things with you at all time.
I already had a deck of playing cards with me every day, when i was starting to play rummikub a ton with friends.
So i decided to make a portable version of the game.

I used a 20G needle that i filed the tip off to fill in the numbers with acrylic paint.
this worked well for me but the golden rule is, wipe your tip and don't use to much paint!
