Tigris & Euphrates

You hold 6 face-down civilization tiles (red temples, blue farms, green markets, black settlements) drawn from a shared bag of ~150, and on your turn you take *up to two actions* freely chosen: place a tile on the board, place/move/withdraw one of your four leaders (king, priest, farmer, trader), play a catastrophe (you have only 2 per game, never replenished), or discard and redraw any number of tiles. Tiles snap onto a 11×16 grid; rivers only accept blue. After two actions you draw back up to 6.

Phase 1: take up to 2 actions in any combination from {place tile, place/move/withdraw leader, play catastrophe, discard and redraw}. Phase 2: every tile placed inside a kingdom awards a victory cube of that color to the matching leader present (or the king as fallback). Phase 3: if your placement bridges two kingdoms each containing a same-colored leader, every shared color triggers an external war — both sides count the warring color across the whole kingdom and reinforce by committing tiles from hand; loser's leader returns home and every warring-color tile in the loser's former kingdom is removed, winner takes one cube per tile removed. Phase 4: if you drop a same-color leader into a rival's kingdom you trigger an internal revolt resolved on red-temple adjacency plus secret red-tile bidding. Game ends when fewer than 2 treasures remain on the board OR the bag empties; final score is the count of cubes in your *smallest* color, ties broken next-lowest.

Every decision asks 'do I extend my lead in a color or shore up my deficit?' — the lowest-color scoring rule means a player with 12 red has zero marginal incentive to score more red, while a player with 2 black is desperate. You weigh tile placement (which color do I generate, which kingdom do I feed, do I bridge?), leader placement (do I trigger a revolt, claim a cube stream, expose myself to attack?), war commitment (spending the very color you most need as ammunition), catastrophe timing (sever a leader from their power base, kill a treasure-rich kingdom), and discard cycling. The option space at a typical turn is large — 6 tiles × dozens of legal squares × 4 leaders × 2 catastrophes — but pruned hard by your bottleneck color.

The dominant skill is *bottleneck identification and threat reading* — knowing which color you and each opponent are starving in, and adjusting placement, leader positioning, and conflict targeting accordingly. Spatial planning is the close second: the board is a 11×16 grid where kingdom adjacency, treasure clustering, and monument 2×2 squares all matter. Tertiary: bid management (revolt and war reinforcement is a sealed-bid auction in the currency you most want to score), and opponent-pressure reading at the social table. Memory and arithmetic are light; the heavy lift is multi-dimensional pressure tracking and the discipline to *not* take a cube in a color you already lead.

Build the rise and fall of Mesopotamian dynasties — your priests, farmers, traders, and king jockey for influence across the fertile crescent, while wars and catastrophes redraw the map.

Iconographic, restrained, classic-Eurogame: terracotta and lapis palette, simple symbolic tile art (temple, farm, market, settlement glyphs), wooden leader disks in four primary colors. Recent reprints (Z-Man 2015, 2024) kept the abstract cleanliness; nothing painterly or romantic — the game's coldness is part of its identity.
