Sky Hopper
An endless vertical bouncer. Steer left and right to land on platforms as your hopper auto-bounces ever higher — climb as far as you can before you fall.
How to play Sky Hopper
Sky Hopper is an endless vertical bouncing arcade game. Your little hopper springs upward all by itself, and your only job is to steer it left and right so it keeps landing on the platforms above. Every time it lands it bounces again automatically, a little higher than before, and the view scrolls up to follow it. There is no finish line: you climb for as long as you can, and the height you reach is your score. Miss the platforms and slip off the bottom of the screen, and the run is over. It takes seconds to understand and a long time to master, which is exactly what makes a good pick-up-and-play arcade game. Play it with one thumb on your phone, tilt your device, or use the arrow keys on a computer.
The goal
Climb as high as possible. The hopper bounces upward on its own the moment it touches a platform from above, so you never press a jump button — you only steer sideways to line up the next landing. The higher you climb, the higher your score. The moment you fall past the bottom edge of the view without catching a platform, the run ends and your height is submitted to the leaderboard. There is no way to win by finishing; the challenge is simply to beat your own best height and climb higher than everyone else.
Getting started
Pick a difficulty and press Start (or tap the play area, or press an arrow key). Your hopper begins on a solid platform near the bottom and immediately springs upward. From then on it bounces automatically every time it lands on a platform. All you do is guide it from side to side so that when it comes back down it lands on something. Press New Game at any time to start a fresh climb, and switch difficulty to change how far apart the platforms are and how tricky they behave.
Steering the hopper
- On a touchscreen, hold the left half of the play area to drift left and the right half to drift right — or use the big ◀ and ▶ buttons below the stage. You can slide your thumb across the screen to change direction instantly.
- On a keyboard, hold the Left Arrow or A to move left and the Right Arrow or D to move right. Let go to stop steering; momentum is not carried, so the hopper stops drifting the instant you release.
- On a phone that supports it, you can also tilt the device: lean it left or right and the hopper leans with it. Tilt only takes over when you are not pressing a key or a button, so the two never fight each other.
- The screen wraps around horizontally. If you steer off the left edge you instantly reappear on the right, and vice versa — use this to grab a platform that is easier to reach around the far side.
Platform types
- Solid platforms (blue) are the bread and butter. They never move and never break, so they give you a dependable bounce every single time. Aim for these whenever you can, especially when you need a safe, predictable landing.
- Moving platforms (green) slide left and right and bounce off the walls. They still give a normal bounce, but you have to time your landing to where the platform will be, not where it is now. Higher difficulties make them move faster.
- Breakable platforms (amber) crumble the instant you bounce off them. They give you exactly one bounce and then they are gone, so never plan to come back to one — always have your next landing lined up before you touch it.
- Platforms are one-way: while you are rising, you pass straight up through them without stopping. You only land — and only bounce — when you are on the way down and cross a platform from above. That is why steering, not timing a jump, is the whole game.
Difficulty levels
Easy spaces the platforms close together, makes them wide, keeps almost all of them solid, and gives you nimble, responsive steering — ideal for learning the feel. Normal widens the gaps, shrinks the platforms, and mixes in more moving and breakable ones. Hard spreads the platforms furthest apart, makes them narrowest, sends the moving ones flying fastest, and sprinkles in the most breakables, so every landing counts. Whichever you choose, the bounce is always strong enough to reach the next platform if you steer well — the difficulty is in the precision, never in an impossible gap. Each difficulty keeps its own leaderboard and its own local best.
Scoring
Your score is simply the height you have climbed — the highest point your hopper has reached, measured from the starting platform. It only ever goes up: dipping back down to catch a lower platform does not cost you anything, because the score records your best height, not your current one. Scores are whole numbers and are capped at 99,999, which is an enormous climb of well over a thousand platforms. When you finally fall, that best height is your final score and is sent to the leaderboard for the difficulty you were playing.
Strategy tips
- Look ahead, not down. Keep your eyes on the platforms coming into view above the hopper and pick your route early, rather than reacting to where you are right now. The bounce is automatic, so planning the next two or three landings beats twitchy last-second corrections.
- Steer gently. Small, brief nudges are usually enough. Slamming fully left then fully right tends to overshoot narrow platforms — ease the hopper over the target and let it drop.
- Use the wrap. When the next good platform is near the opposite edge, it is often faster to slip off one side and reappear on the other than to cross the whole screen. The wrap is a tool, not just a hazard.
- Respect breakable (amber) platforms. Treat them as single-use stepping stones. Only aim for one when you can already see a safe landing beyond it, because you cannot bounce on it twice.
- Time moving (green) platforms by aiming where they are going, not where they are. Land near the middle of a moving platform to give yourself the biggest margin as it slides, and remember they reverse when they hit a wall.
Frequently asked questions
How is my score calculated?
Your score is the height you climb — the highest point the hopper reaches, counted from the starting platform and rounded to a whole number. It never decreases while you play, and it is capped at 99,999. When you fall, that best height becomes your final score for the leaderboard.
What ends a run?
You lose when the hopper drops below the bottom edge of the visible area without catching a platform. Because the view only ever scrolls up to follow your highest point, once you fall far enough below it there is no way back and the run ends.
What happens at the left and right edges?
The world wraps horizontally. Steer off the left edge and you reappear from the right, and off the right edge you reappear from the left. You can use this to reach a platform that is closer around the far side of the screen.
Is there a reduced-motion option?
Yes. If your device is set to “reduce motion”, Sky Hopper automatically drops the drifting background stars and other decorative motion, leaving only the essential gameplay. The game itself plays exactly the same either way.
Does it work offline?
Yes. Once the page has loaded, Sky Hopper runs entirely in your browser with no internet connection. Any best heights you set offline are stored on your device and upload automatically the next time you are online and signed in.
