Blacksmith — free browser game

Blacksmith is a craft/strategy game where you hammer a glowing iron bar on the anvil into a target silhouette. The stage shows an 8-cell iron bar; each cell starts 8 units tall and a dashed outline above shows the target profile of the next piece (axe head, horseshoe, chisel, and so on). Click, tap or press 1-8 to bring the hammer down on a cell: its height drops. How far it drops depends on heat — at heat 66+ each strike shaves 2 units, below that 1 unit, and at heat 0 the hammer kisses the cold iron and nothing happens. Every strike spends 8 heat, and the iron also loses 4 heat per second to the air. If any cell drops below its target the iron is crushed and the game ends — so the last hits must usually be done at lower heat (1 unit each) rather than hot (where 2 units would overshoot). Press the Forge button (or F) to bellow the fire for 1.4 seconds — heat ramps back to 100, but you can't strike during the heat-up and the piece timer keeps running. When all 8 cells match the target the piece is forged: score +1, a new target appears, the bar resets to full height and the heat carries over. Each piece has a time budget that drops from 25 s to 12 s as you progress. Strategy: open hot for ×2 shaping, switch to other cells or wait while heat drains as you close in on the target, and don't over-forge — every second in the bellows is one less for hammering.
