4 Monkeys: Expansion

Includes 2 mini expansions:

- Blind Monkey, suggested by Vlaada Chvátil.

Cover one of your tiles to avoid giving info about your tiles.

(and make it a bit harder to you)

- Interferences by Toni Serradesanferm.

Interferences are making the test more difficult, they interfere with the available tiles so you never know all of them for sure.
