Every game here has one system in it that is more interesting than it looks from the outside. A Moon that is calculated instead of stored. A replay that is neither a video nor your keystrokes. A monster deciding, sixty times a second, whether a shelf is between you and it.

• Why a browser game can start in secondsWhat happens between clicking play and the first frame, and why having no engine to boot changes everything.
• How Moon Miner builds a Moon out of one numberThe world is never stored anywhere. One seed and a hash decide every rock and every ore vein the moment your drill arrives.
• Offline earnings with no server at allCozy Fishing pays you for time away using one saved timestamp, one subtraction, and a cap that stops the maths from breaking.
• How Void Daggers replays your whole runNot a video and not your inputs, but a flipbook of positions twenty times a second, and the reason it had to be built that way.
• Why idle game numbers explodeCosts multiply while damage adds, which is the entire difficulty curve, and eventually forces a number like 1.01e+15 onto the screen.
• Light against the dark: how Deepwick's light worksOne number is your health, your fuel and your eyesight, and the darkness is a black sheet with a soft hole erased through it.
• How a monster knows it can see youLine of sight in AISLE 7: a straight line walked across a grid of floor squares, what counts as cover, and the twist about what the monster already knows.
