Neverball is a 3D ball-rolling game in the lineage of Marble Madness and Super Monkey Ball. You guide a ball through obstacle courses by tilting the ground beneath it using your mouse, keyboard, or joystick. The ball has real physics and real momentum, which means every slight tilt matters, every overcorrection sends you careening toward an edge, and every narrow bridge becomes a test of nerve. The floor moves. The ball reacts. You try not to fall into the void. Each level has a simple goal: collect enough coins to activate the exit pad, then reach it before time runs out. Yellow coins are worth 1, red coins 5, blue coins 10. Collect 100 total and you earn an extra life. The levels start gentle enough, teaching you how the tilt-and-roll relationship works. Then they introduce moving platforms. Then mazes. Then pushers that shove your ball sideways. Then narrow ramps over bottomless drops with moving obstacles and a 30-second timer. The difficulty curve goes from "pleasant Sunday puzzle" to "controller-gripping precision platformer" across 183 levels. Three highscore categories per level reward different playstyles: most coins collected, fastest time to unlock the goal, and fastest time to complete the level. Speedrunning and coin-optimization runs require completely different approaches to the same course, which gives every level at least two reasons to replay it.
A little game of steady hands. Slide, tilt, and guide a loose nut along a wobbly wire home to its robot. Hold the nut, drag it along the wire, and tilt it through every hill and dip without touching the rail. Dock it into the robot's socket to finish the fix. Six short courses teach one thing at a time: holding steady, tilting through bends, and reading the camera. Then the Workshop turns it up with rolling hills, tighter bores, and a three-crest finale. Three stars for a clean run. Every touch of the wire costs a star. Six courses across two chapters; each finish unlocks the next. Mouse, keyboard, or touch: drag to move, wheel or Q/E to tilt, right-drag to orbit. Resume any run exactly where you left it. Best stars are kept. Built with Rust + WebAssembly, WebGPU rendering, and Blender models. Needs a WebGPU browser: a recent Chrome, Edge, or Safari on a supported device.
You have to manipulate different shapes of sand blocks that fall from the top of the screen and arrange them in a way that they form complete horizontal rows at the bottom of the screen. The more rows you clear, the more points you get and the higher your level goes. Rotate and move the blocks to fit them better in the available space, but don't let them stack up too high or touch the top of the screen or you'll lose. This game is fun, challenging and relaxing at the same time. It tests your spatial skills, your reflexes and your creativity.

You are a translucent slime the size of a small animal, and the planet under you is covered in things bigger than you are. Roll over the grass and swallow it. Then the flowers, then the fence, then the sheep that was ignoring you a minute ago. Every bite makes you heavier, and every kilogram of mass moves the edge of what you can eat a little further out. There is nothing to fail. No timers, no enemies, no currency to manage. A building too large to swallow simply pushes back and bends you around it, until it does not. The pleasure is watching the scale of the world turn over: the tree that filled your screen becomes a snack, the car becomes a crumb, the skyscraper becomes the next goal. Clear one planet and the galaxy map opens the next, each with its own look, its own skyline and its own ladder of things to devour. Hats, trails and skins are yours to collect along the way, purely so your slime looks the way you want while it eats a world. How to play: hold the left mouse button and drag where you want to roll, or use WASD and the arrows. On a phone, touch the screen and drag; the slime follows your finger. Everything else is automatic.
Bounce Park is a whole indoor trampoline park that you can throw yourself around in. You time your jumps, flip and twist through the air, try to land on your feet, and see how big a combo you can build before it all goes wrong. Bouncing is simple to pick up. Press Jump at the bottom of the bed for a power bounce and hold it to go higher. Once you're in the air, hold a trick key and steer to flip and twist, and tuck or pike to change how fast you spin. Every bounce is graded on your timing, so a run of perfect ones will carry you right up to the roof. Land cleanly and your combo keeps going. Land badly and you ragdoll across the mats in front of everyone. The park is one big open hall and you can walk, sprint and jump wherever you like. There are rows of beds to hop between and chain combos across, angled wall trampolines to run up and kick off, a foam pit for the tricks you're not sure you can land, a dodgeball court with loose balls, a ninja course of blocks, ramps and gaps, and a set of pro beds for when you want serious height. There are no levels and no timers, so you can spend your time however you want. It's best with other people. Up to 16 players share the same park in real time, and you can bounce on the same bed as a friend, watch each other's combos come through in the feed and react when someone lands something ridiculous. There's lobby chat, an emote wheel with waves, claps, cheers, facepalms and a dance, and quick reactions for when words aren't enough. Before you step onto the beds you can set up your character with your own hair, hair colour, top, bottoms and colours. If you like chasing numbers, there are global leaderboards for best combo and highest bounce, which you can also filter to your friends or to the players ranked around you, plus a live board for the lobby you're in. The game keeps lifetime stats for your bounces, flips, twists, skills landed and foam dives, and there are achievements to find along the way, from your first flip to visiting every corner of the park. Bounce Park runs straight in the browser with nothing to install, and it works with keyboard, gamepad or touch, so you can play on a desktop, a laptop or a phone. Jump in, find a bed, and see how high you can go.

Pull back, let it fly, and watch them fall. Bowfall is ragdoll archery on floating islands. How far you pull sets the arrow's speed, damage and weight, and nothing draws the arc for you, so every shot is your own read. A killing headshot knocks the head clean off. A heavy hit to the chest shoves an archer off the edge, and gravity does the rest. The waves never end, and a warden shows up every fifth one. Coins buy permanent upgrades and new arrows, 46 to collect, from poison and hooks to a chainsaw. Clear wave 3 and the Daily hill opens: the same islands for everyone, the base bow, one global leaderboard. How high can you climb?
Pool Merge Mania is a clever spin on classic pool where bouncing shots meet merging mayhem. Fire balls into the arena, watch them collide and combine into higher-level spheres, and strategize to keep your table under the 15-ball limit. Quick merges mean tighter control, so aim smart and stay in the game!
Take your built up anger out against evil shoppers that stop in the middle of aisles, blocking the way between you and your overpriced grocery-slop.

A little world of reactions, one grain at a time. ▎ Pick an element and draw it into the world. Sand piles up, water finds its level, oil floats, smoke drifts away. Then things start to react: ▎ - Heat sand until it fuses into glass, or melt stone into lava ▎ - Pour water on lava and watch a new shoreline hiss into stone ▎ - Wire a battery to a lamp and light it up ▎ - Plant seeds in wet soil and watch them sprout and climb ▎ - Chill a cloud until it rains, or snows ▎ - Set off blast powder and follow the chain reaction ▎ - Neutralise acid with baking soda, rust metal in salt water, dissolve salt and boil it back out ▎ There's no score and no timer. Try an idea, see what happens, undo and try another.

Haul a panda back on a giant slingshot, let go, and watch it tuck into a ball and barrel down the lane. TEN FRAMES, REAL STRIKES AND SPARES. The lane has a proper oil pattern — slick through the front half, dry at the back — so a delivery with some angle on it hooks into the pocket instead of running straight down the boards. PULL BACK FOR POWER, DRAG ACROSS TO AIM. The two are separate, so you can change your line without winding the cord up any harder. Let go and the bands snap back on their own springs. GET UP AND WALK. Stand up at any time and take the concourse in first person. The alley is a bamboo grove with a row of lit lanes running through it, and every lane is live — walk to a free one and claim it whenever you like. Plays in the browser. Keyboard and mouse.
Unicorn land needs more rainbows, and the best way to create rainbows is to perform gnarly combos! Backflip over the hills, connect your combos with wheelies, and show the unicorns what it’s like to shred!
You never touch the car. Dizzy Dish gives you exactly one control: the spin of the giant dish the car is sitting in. Everything else is physics. Friction between the turning floor and the wheels drags the car around with it, centrifugal force throws it outward and up the sloping wall, and gravity pulls it back down toward the middle the moment you ease off. Somewhere between those forces is a speed that holds the car exactly where you want it. Find it, steer the car into the dimple half way out from the centre, and keep it there for two seconds to win. One warning, because it is the thing everyone tries first: spinning the other way does not pull the car back in. Centrifugal force does not care which direction you turn. The only way back to the middle is to let the spin die down. Hold LEFT or RIGHT, or push a gamepad stick. That is the whole game.
Spectral Horn is a 2D optical physics puzzle game handcrafted for js13kGames 2026, engineered strictly to fit within the 13 kB zip limit with zero external libraries or assets. In 1666, Sir Isaac Newton stuck a glass prism into a sunbeam and proved that white light is a chaotic rainbow party. Naturally, we asked the only logical follow-up question of modern science: What if, instead of a prism, we used a unicorn horn? Guide white beams into the crystalline horn of a celestial unicorn, disperse light across physical wavelengths using real Cauchy dispersion, and exploit total internal reflection to bounce rays around obsidian shields. Every bounce and refraction is calculated analytically in real time across 17 handcrafted levels. Controls: Drag the unicorn to move, rotate the orbit ring to aim, and use the step buttons for 0.5° micro-adjustments until the spectral sensors lock at 100%. Full touch and mobile support with vertical finger offset. Created by Filip Paulů — https://paulu.cz/
