Project L

You must perform exactly 3 actions on your turn; unless a rule says otherwise you may perform any of the available actions in any order and any number of times (the Master action is the only exception). (p. 6)

Master lets you place up to one piece from your supply into each puzzle above your Player mat, you may skip puzzles, and you may only use Master once per turn, so you cannot place more than one piece on the same puzzle with Master. (p. 6)

Upgrade A gives you a new level‑1 piece from the reserve; Upgrade B lets you return a piece from your supply and take a replacement that is the same level, any lower level, or one level higher, and if the higher level is empty you take from the next available level. (p. 6)

When a puzzle is completed you first return all pieces from that puzzle to your personal supply, then you take the new piece depicted on the puzzle (or, if that type is unavailable, a piece from the next available level) and place the puzzle face down on your Victory Point pile. (p. 6)

When the Black puzzle deck is empty the end is triggered: finish the current round and then play one final round; Black puzzles taken at that point are not replaced, and from then on each player may take at most one Black puzzle per turn. (p. 6)

After the final round each player may place any number of pieces into their unfinished puzzles (following normal Place rules) but each piece placed costs 1 point, you must perform all Finishing Touches before any puzzle is considered completed, and completed puzzles gained this way do not grant the bonus piece.
