Nobody remembered who built it. Some said a physicist who’d gone feral. Others said a carnival barker who’d learned the wrong secrets. But everyone knew the rules: you walked in, paid no money—just a hair from your head and a drop of your spit—and the shack played a game with you.

They called it the Size Game.

And somewhere inside, in the dusty dark, a pair of dice tumbled across old bone— click-clack, click-clack —a sound like the world’s smallest thunder.

Out past the rusted grain silos and the crooked welcome sign that read “Littleton—Population: 42,” there stood a shack. No bigger than a two-car garage, its roof patched with tin and tar, its windows glowing a faint, sickly amber.

The game was simple. A wooden counter. Two bowls. A set of dice carved from old bone. You rolled. The shack rolled back. But the stakes weren’t numbers.

Most folks in Littleton learned to stay away. But every so often, a teenager dared another. Or a farmer, fed up with a bad harvest, thought being bigger might help. Or a lonely woman, tired of being overlooked, thought being smaller might make her disappear for real.
