Choose 2–4 participants. One human can play against AI rivals on this page.
At least two active guilds are required.
How to play
Build the most prestigious guild by collecting gems, purchasing developments, and attracting noble patrons.
Your turn
Choose exactly one action:
Take gems. Take one gem from each of three different available colors. If fewer than three colors remain, take one from each available color instead. Alternatively, take two gems of one color when at least four of that color were in the bank before your turn.
Reserve a development. Reserve a visible card or the hidden top card of a level. You may hold at most three reserved cards. Gain one gold wildcard if the bank has one; reserving is still allowed when it does not.
Buy a development. Buy a visible or previously reserved card by paying its cost. Return spent gems to the bank.
Developments and gold
Every development stays in front of you and permanently reduces future costs of its color by one.
Some developments also award prestige. Higher-level cards are usually more expensive and more valuable.
Gold is a wildcard used only when buying a development. It can replace any missing colored gem after discounts are applied.
End of a turn
You may keep no more than ten gem tokens, including gold. Return excess tokens to the bank.
A noble joins automatically when your permanent development discounts meet its requirements. If several nobles qualify, choose one. Noble requirements do not spend cards or gems.
Winning
Reaching 15 prestige starts the final round. Play continues until every participant has completed the same number of turns. The highest prestige wins; tied players are ranked by the fewest purchased development cards.
