Tzolk'in: El Calendario Maya

You must either place one or more available workers or pick up one or more of your workers; you cannot do both or skip your turn (your first turn will always be a placement turn). (page 6)

You pay corn equal to the action-space number for each worker placed, plus an additional cost based on how many workers you place that turn as indicated on your player board (the board shows the cumulative and per-worker breakdown). (page 6)

For each worker picked up you may either perform the action where it stood, perform a lower-numbered action on the same gear by paying 1 corn per step back, or do nothing; you pick them up and resolve the chosen effects sequentially, so order matters. (page 6)

On a Food Day (there are four per game) after everyone has taken a turn you must pay 2 corn for each worker in play (on the gears or in front of you); you must feed as many workers as you can and lose 3 victory points for each worker you fail to feed, while farm buildings can reduce feeding costs. (pages 13, 11)

At the start of your turn, if you have 2 or fewer corn you may beg: discard all your corn and take 3 from the bank, but this angers the gods so you must move down one step on a temple; if you must place but cannot and have no workers on gears you must beg (with a rare special case if you are already at the bottom of every temple). (pages 6, 11)

The Starting Player Space gives you all corn accumulated on the gear tooth immediately, returns that worker to you at the end of the round, transfers the Starting Player Marker, and may let you advance the calendar 2 days with restrictions; temple top steps are exclusive to one player and when you reach a top step you flip your board lighter-side-up (granting calendar-speed privileges).
