Tzolk'in: The Mayan Calendar: Mini Expansion 2
Originally given away in the Gathering of Friends 2013 convention giftbags, this mini expansion includes one new monument and one new starting wealth tile.
The monument tile will reward users richly for building it is early as possible, while the new starting wealth tile gives the player a head start on wood and corn, but penalizes on the god track for these corn and wood riches.

Note: Our supply of this promo was cut a bit off-center, making them distinguishable from the tiles in the base game. However, the effect on game play is very minor, as game set-up is the only time this would matter. Once the game set-up is complete, this will have no effect on the game. While it shouldn't pose a problem if you just shuffle the tiles without looking too closely, if you wish for a completely unbiased game set-up, we recommend using a drawstring bag to keep players from being able to distinguish the slightly off-center tiles.
