Indus 2500 BCE is a flip-and-write game in which on each turn players either pick a terrain card from the market and draw the pattern as shown (including walls to protect against calamities) or reserve resources to build more advance buildings. The game continues until a calamity card shows up to destroy areas of the meticulously built city. The game ends immediately once a second calamity card is drawn and resolved. Points can be earned from matching the revealed score cards, collecting artefacts, and building advance structures, walls, and the most types of terrains. Whoever has the most victory points wins. —description from the designer
