I havent read the description field of the Micro entry, but here's my translation. I hope this one's clear enough. If not, gimme a shout.
Mondo Micro is an expansion for 2 players at the age of 8 and up.
Playingtime: 15 Minutes
Put the Micro-Tableau in the middle of the table in between the both of you.
The game is being played with the rules of the Beginner game with one exception:
Set the timer to 3 minutes.
Variant: Before a turn, search for any 2 equal Tiles (different animals are allowed).
Put 1 of them with random alignment on the darker field of 1 of the tableau.
The other player uses the 2nd tile with the same alignment.
Okay, so this is a "mini" version of the game, where you use these boards instead of the normal ones, and you play for 3 minutes? And to make it a little harder, you both have the same "starting tile" in the dark space?
