River Valley Glassworks

No — on your turn you must choose exactly one action: either a Place & Gather or a Draw; you cannot do both (Rulebook p.2).

Place 1 piece on a tile whose corner shape matches (or place 2 identical-shape pieces on any tile), then choose 1 adjacent river tile and gather all glass from that tile (the lake is not a river tile) (Rulebook p.2).

Shapes matter for placing and gathering from the river, while colors matter when adding pieces to your glassworks — new colors go into the next empty column left-to-right and existing colors fill their matching column bottom-to-top (Rulebook pp.2–3).

If a piece won’t fit because a column is full or you already have 7 colors, place it in overflow; when drawing from the lake, your pan can hold only 5 and any excess you choose goes to overflow (Rulebook pp.3–4).

When you take a Draw action you choose 4 pieces and add them to your pan (not your glassworks); afterwards refill the lake to 5 from the bag, and remember your pan max is 5 with any overage to overflow (Rulebook p.3).

When a player reaches or passes 17 on the inventory track they trigger the end; immediately any player with fewer than 3 pieces in their pan draws to 3, finish the current round so everyone has the same number of turns, then each player takes one final turn before final scoring (Rulebook p.4).
