JULKEN

Twelve microgames set in a repair workshop: saw, hammer, drill, wrench, paint, solder, sweep, lathe, sand, level, clamp and patch. Each gives you about five seconds and a one-word instruction. Four lives, a tempo that rises with every clear, and a four-stage boss. Endless mode is live; story mode is still being made.

A falling-sand sandbox with forty-one elements. Sand piles up, water flows, oil floats on it and burns, lava sets things alight, plants grow where there is water, bacteria eat what dies. Every element has a density, an ignition point and a melting point, so a lot of pairs do something when they meet. Draw with a brush, a line, a rectangle or a flood fill, and save what you build.

Snake on a twenty by twenty grid, six ways: classic, fast, chill, no walls, a speed ramp that keeps accelerating, and an autoplay mode where the game plays itself. Eating quickly builds a combo. A few skins.

Tower defence on a space station. Eight tower types (laser, rocket, plasma, tesla, sniper, flame, railgun, freeze) and one ultimate, the Annihilator, against aliens that come shielded, split when hit, regenerate, or fly over the path. Four maps: an easy single path, a hard set of multiple paths, and endless versions of both. Towers upgrade and sell back.

One button. Tap to flap and do not hit the pipes. The gap stays the same size, the pipes get faster the longer you last, and your best score is kept. That is all there is to it.

A vertical space shooter with six modes: classic waves with a boss every fifth wave, survival, time attack, boss rush, a five-bosses-at-once challenge, and a zen mode with infinite health and no bosses. Power-ups drop from about a quarter of the enemies you destroy, and there are achievements to chase.

Hold space to thrust, let go to fall. Four modes: dodge, weaving through skyscrapers; shooter, with a boss every hundred points; rift runner, where you chain gates to stay alive; and blackout, flown by headlight in the dark. There is also a Windows build for anyone whose browser drops frames.

Steer through traffic, pick up coins, keep a combo going, and spend the coins on three power-ups: five seconds of flying over everything, a coin rush, and ten seconds of thinner traffic. The oldest arcade game here, rebuilt in 2025.

Guess the number. Five difficulties, from one to fifty in six tries up to one to a million in fifty. Wins earn tokens, and tokens buy hints: even or odd, the last digit, the digit sum, or a narrower range. A streak counter, achievements, and a daily number.

The first game on this site. Press space to earn points, buy generators that press it for you, then ascend to start over with a permanent bonus. Thirty-one generators, twenty-five upgrades, forty-three achievements, and a combo meter for fast pressing. Saves export and import as text.
