THE FULL READ
Splendor is the gateway Euro every veteran hands to a new player on day one. The teach takes five minutes (take three gems, buy a card, repeat); the strategy goes deep enough to reward 20+ plays. Almost every modern hobby-gaming convert had a Splendor session early in their journey.
The core engine-building loop is the magic. Cards bought give you a permanent gem of one colour, reducing the cost of future cards. The first card costs raw gems from the pool; the tenth costs almost nothing because your earlier cards discount everything. Recognising which colour to commit to early is the entire mid-game.
The single biggest tactical decision is whether to chase nobles or chase points. Nobles (the visible aristocrat cards) give 3 free points each but require specific gem-colour balances. A player who can claim two nobles wins roughly 75% of games — but committing to noble requirements early forces you to buy cards in colours you might not otherwise want. The community consensus is that one noble is target play; two is great play; three is rare.
Reserving cards is the misunderstood mechanic. New players reserve cards they want to buy; veterans reserve cards they want to *deny opponents*. A card you reserve is unavailable to anyone else, and you get a gold (wild) token in return. Reserving an opponent's noble-completing card with a gold pickup is often a 6-point swing.
The two-player game is its own beast. Tempo and denial dominate; the optimal play involves more reservations than purchases through the mid-game. The four-player game is looser and more card-availability-driven. Three-player is the most-cited sweet spot — enough opponents to matter, not enough chaos to defeat strategy.
Cities of Splendor (2017 expansion) is universally considered an improvement. The Cities module replaces nobles with city cards that change the win condition; the Trading Post module adds bonuses for collecting specific cards. Buy the expansion immediately if you've played the base game more than 10 times.
