Chalk Empire

A turn based chalkboard strategy game. Draw outposts, end the turn, and watch your chalk creep outward while ink spills bloom underneath it and eat your coverage. Spend the dust your territory earns on more outposts, growth boosts, an eraser for the spills, and golden fixative that makes a patch ink proof forever. Cover half the board and the field itself expands, shrinking everything so there is always more room to claim. Chalk 90 percent of it to win, on Chill, Normal or Extreme.

How to play

You are drawing an empire in chalk on a school slate. Click the board to draw an outpost, then hit End turn and every patch of chalk you own creeps outward. Territory earns chalk dust, dust buys more chalk, and the board fills. Cover 90 percent of it and you win.

Your first outpost is free, so the game opens with a single click anywhere. There is no way to lose and no timer: wet ink can eat your coverage and stall you, but it can never end the run.

The win fires the instant you cross 90 percent, not at the end of the turn, so a boost or a well aimed erase can take it there and then. When it lands you can keep playing on the same board or start a fresh run.

A turn in progress: two chalk patches spreading, a golden ink-proof one on the right, two ink spills eating the board, and the dashed ghost showing where your next outpost would land.

Reading the slate

The HUD above the board tracks the run: which turn you are on, how many times the field has grown, your dust, and the coverage you are chasing. Coverage is measured on the board you can see, so it drops the moment the field expands.

Turn 7, the field already doubled once, 148 dust banked, and 52 percent of the slate under chalk. The board expands at 50 percent and the run is won at 90.

What dust buys

Every tool has its own price, and every purchase makes the next one of that kind about a fifth dearer, so a run is a long argument about what to spend on.

✏️ Outpost (20 dust, first one free). Click clean board and a new patch of chalk appears there, ready to spread. You cannot draw on top of wet ink, and the dashed ring under your cursor turns red when the spot is inked or you are short of dust.

🌊 Growth boost (15 dust). Every patch you own surges outward at once, without waiting for the turn to end. Cheap, immediate, and it stacks with the growth you get anyway.

🧽 Eraser (25 dust). Click a spill and it is gone. The chalk it was covering counts again straight away, so a well timed erase can be worth more than a new outpost.

✨ Fixative (35 dust). Click one of your own patches and it turns gold: ink can still spill over it, but it will never blank it out again. Permanent, and the only true defence in the game.

Ink is the whole problem

From the second turn on, a spill has a coin flip chance of blooming somewhere on the board each turn, up to eight of them at once. They spread every turn just like your chalk does, and any chalk under wet ink stops counting toward coverage and toward your income. Erase them, gold plate what matters, or draw somewhere else.

The field grows

The twist: reach 50 percent coverage at the end of a turn and the board itself expands. Everything on it, your chalk and the ink alike, shrinks toward the centre and the field level ticks up. Coverage falls back, but you have not lost anything: it is the same chalk in a bigger world, and there is suddenly room to grow again.

Hit half the board and the ring sweeps out: the same territory, redrawn smaller, with fresh space around it. Expansions repeat until coverage settles back under half.

Your income does not shrink

Dust is paid on the absolute area of your chalk, not the percentage showing on screen, so an expansion never cuts your earnings. That is what makes the cycle work: grow, expand, keep the income, fill the bigger board, and push for 90 percent before the ink outpaces you.

Difficulty

Three settings, and they change how much chalk you get for your dust rather than how the ink behaves. Switching resets the run.

Chill. Big new outposts and fast growth every turn. The board fills quickly and expansions come thick and fast.

Normal. Middling patches, steady spread. You have to think about where the ink is going.

Extreme. Tiny outposts that barely creep. Ink grows at the same speed it always does, which makes erasers and fixative the real game.

Tips

Spread out. Two patches on top of each other cover the same ground once, so overlap is wasted dust.
A patch stops growing once it hits its size cap, so late runs are won by having more outposts, not bigger ones.
Erase early. The price of an eraser has nothing to do with the size of the spill, and a spill you leave alone grows every single turn.
Save fixative for your biggest patch, especially one an ink spill is already drifting toward.
Boost starts as the cheapest thing on the tray. When you are a few percent short of an expansion, it is usually the fastest way over the line.
Watch the ghost ring before you click: red means wet ink, and the dust is not spent until the chalk lands.
