Klocky

Tooth by tooth, wheel by wheel
The world moves too fast.

Under the lamp lies an old drawing. On the bench, a box of brass and steel: gears, a pallet fork, a balance wheel, a mainspring. No timer, no failing, no one hurrying you. Just the next part, and the place it belongs.

Slip the pallet fork into the escape wheel, then drop the balance wheel's little red pin into the fork. The moment they meet, the whole machine starts to tick, one beat at a time.

Every tooth really drives the next
Nothing in Klocky is a canned animation. Tooth counts, ratios, arbors and layers are all worked out like a real clock. How the machine moves is decided by the parts you put in.

The 70-tooth centre wheel drives the third wheel's 7-leaf pinion; the 66-tooth third wheel drives the seconds wheel's 11-leaf pinion: 70/7 × 66/11 = 60. So the seconds hand turns once a minute, and the minute hand once an hour.

Gears only mesh on the same layer, at exactly the right distance. Close three gears into a loop and the machine locks up.

As long as the parts truly work together, they can sit anywhere. Your layout can differ from the drawing and it will still run.

One drawing, one step
Every machine has a book of hand-drawn assembly drawings. The open page tells you what to fit next: click a line on the list and the part lights up; set it to the layer written there, drag it into place, and with a green flash it's in. Finish a sheet, turn to the next.

Open a book. Discover a machine's story.
Every machine has a history. Why did watchmakers make an escapement rotate? How can a row of steel teeth play a tune? How did people use gears to bring the heavens down to a workbench?

Open a machine's book and explore its history, workings and ingenious details through text and engraving-style illustrations. Read a little of its story, then turn to the assembly drawings and build the mechanism with your own hands. You can always turn back while building to discover why a particular wheel belongs where it does.30+ machines
The full game is planned to include more than 30 machines. Start with a little counter that counts seconds, then explore clocks, musical mechanisms, automata, astronomical instruments and famous landmark clocks. For example:

Rose engine　The paper turns slowly on a turntable while a crank pushes the pen back and forth. The two motions add up into a many-layered flower.

Calendar moon clock　A wheel that turns once a day steps the date, the weekday and the moon phase on by one each day, and the moon slowly waxes and wanes in its arched window.

Orrery　Mercury, Venus, Earth and Mars circle the sun at their true relative speeds. The moon rides on the tip of Earth's arm, carried round by a small gear rolling on a fixed wheel.

The Blacksmith　Four cams on a camshaft push their followers, and the little smith on the stand swings his hammer, nods, works the bellows and turns the iron with his tongs.

Famous clocks from around the world　Assemble world-famous clocks such as the Prague Astronomical Clock with your own hands. Bring the mechanical wonders of town squares and clock towers to life on your workbench.

Put on your headphones
Inside a single tick, many parts touch lightly. Each has its own voice: the fine click of gears meeting, the soft snap of a star wheel jumping a notch, the whirr of a fan, the pluck of a music comb. Fit different parts, and the machine sounds different.

The ticking is recorded from real clocks, with four sets to choose from: pocket watch, alarm clock, mantel clock and wall clock.Features
More than 30 machines planned for the full game, from clocks and astronomical instruments to automata and landmark clocks

A book for every machine, with its history, an explanation of its workings, engraving-style illustrations and hand-drawn assembly drawings

Mechanisms worked out like real gears: ratios, escapements, jump springs, cams, count wheels, planetary gears

Parts stack in layers: cut away to any layer, or pick up the whole machine and turn it in your hands

Speed up time, or skip to the next hour, day or year and watch the calendar turn and the moon wax and wane
