Urban Sketchers

Yes — using a white die on a color-coded action requires you to pay the cost shown; if another player already used that color this round you pay that player the difference in die values (1 money per pip), otherwise you pay the bank (p.5).

Yes, you may sketch as many cards as you want in the same sketchbook during a Sketch action, but you pay 1 money for the second card, 2 for the third, etc., tracked separately per sketchbook; resource costs and any discounts still apply for each card (p.6).

The Supply action is colorless and any die may be placed in an empty supply space; it is always free and you receive resources equal to the net difference between the die you placed and the die tile above that space (p.5, p.6).

When you publish you gain victory points (based on card count), money equal to the number of cards, the theme tiles shown on the cards, advances on the Published and Prestige tracks (including any bonuses), and then you discard all cards and bonus tiles from that sketchbook (pp.6–7, p.10).

You may flip pairs of different theme tiles on your turn to gain the benefit shown between them, each tile can only be flipped once but you may flip as many pairs as you wish; during a Funding action you may flip matching theme tiles to gain +3 money per tile flipped (p.8).

The game ends after the round in which the Total published sketchbooks token reaches the player-count target (6/9/12 spaces); then unpublished sketchbooks are discarded but score as if published for victory points only (no money, theme tiles, or Prestige), followed by theme-set and track scoring (p.9).
