About the game
Civiliz8n squeezes the city-builder into a few minutes. You start with a small hexagonal map dotted with trees and a handful of turns. Every turn the game offers three random buildings; you choose one and set it down on a hex touching the last one you placed. Your settlement grows as a winding trail across the map, and each piece scores in its own way.
Huts are worth a point and hand you a free extra hut. Gardens score more when three of them form a group. A meeting circle pays a big bonus once every hex around it is filled. Shrines are valuable only when kept away from other shrines, temples like to be surrounded by variety, and foresters clear the trees next to them, scoring for every tree cut. Trees block building until someone clears them, and if your trail ends with no free hex to move to, the game is over early.
There are three cities to choose from, Nineveh with 10 turns, Persepolis with 15 and Babylon with 20, plus a Hammurabi mode that plays all three in a row and adds up the score.
Playing it here
Civiliz8n is a CHIP-8 program. CHIP-8 is a simple virtual machine from 1977, created for hobby computers like the COSMAC VIP, and people still write new games for it. This one targets XO-CHIP, a modern extension with extra colours, more memory and better sound, and was made for Octojam 2, a yearly CHIP-8 game jam. It runs here in the Octo emulator, with the speed and colours chosen for it in the archive.
Click Play, then press 1, 2, 3 or 4 to pick a city. The game is played with the number keys and the six letter keys on the left of the keyboard. F2 saves the state of the emulator at any moment and F4 brings it back.

A few things worth knowing
Stick to the letter keys. In this game the arrow keys and Space also count as W, A, S, D and E, so they place buildings in directions that do not match the arrows. Q W E A S D map neatly onto the six sides of a hex.
Plan your exit. Each building must go next to the previous one, so do not wall yourself into a corner of trees and buildings. A forester early on opens up room as well as scoring.
Shrines need space, meeting circles need neighbours. A shrine only pays if no other shrine is within two hexes, while a meeting circle wants all six of its sides filled. Placing them with that in mind is where the big scores come from. The source code lists a Hammurabi high score of 185, if you want a target.
