We need a redesign for our cards.
Each card file is 63*88mm, 3mm bleeds - 69mm*94mm, should be done vector and CMYK, because it will be printed.
The game includes 108 cards (don't worry, no needs to design them all), it has:
numbers from 1 to 20 on the yellow background
from 6 to 20 on the green background
+1, +2, +3, +4, +5 on the white background with our logo,
special card on blue background (now it's "+", but it's not necessary, it could be anything with positive meaning, because it's kind of joker card)
circle on red background. We don't want see this circle anymore, it should be replaced to something else. It's the worst card, so the player who draws should understand "oops, that's not good!".
What we need:
now cards look boring and simple, it should look funnier, people hold them and know it's a fun game.
We expect in return 5 cards:
1) any number on the green background
2) any number on the yellow bg.
3) +5 on the white bg with our logo. The white card means the next person should draw cards, so we're fine with our logo on the background, but if you can make up something more interesting, would be great.
4) something on the red bg, what means danger, for a card which could be hard to get rid of
5) something positive on the blue bg, what means you have 2 turns instead of 1, can play this card on any card and place any card on top of it (could sound complicated, just know it's a good card to have)
I've written "color of the background", but these colors are not necessary to come from the background, just overall color of the card should have these primary colors.
All cards should have a big number or whatever in the center and small copies in 2 corners as on standard cards.
Would be great to not make your own font for digits, because we should be able to copy the design to all numbers used.
I have uploaded our logo and current basic design of our cards.
