How to play Platform Hop
Run right, jump the gaps
Hold a direction to move and tap jump to leave the platform. Falling below the platforms ends the run. Your result is how far right you got.
Two jumps per time in the air
One from the platform, and one more while you are still airborne. Touching down resets them, so the second jump is something to spend rather than something to lean on.
Platforms pass under you but not through you
A platform is one-way: rising into it from underneath carries you straight through, while falling onto it from above lands you on top. This is the standard way these games behave, and it matters — if platforms blocked you from below, a mistimed jump under an overhang would end the run in a way that looks like a bug.
Every gap can be jumped, at any height
The horizontal space between platforms and the height difference between them are both derived from your actual jump — the height you can reach and the distance you cover while airborne — with a safety margin, because nobody jumps from the very edge every time. Nothing is written in as a fixed number of pixels, so the gaps cannot drift out of reach if the movement is ever adjusted.
The margin is deliberate
The allowed gap is about seventy per cent of the full jump distance and the allowed rise about sixty per cent of the full jump height. Sized at a hundred per cent, a gap would be technically jumpable and in practice a coin toss.
On-screen buttons or a keyboard
On a touchscreen there are three large pads along the bottom: left, jump and right. On a keyboard the arrow keys move and the space bar jumps.
Platform Hop Tips and Strategy
Backtracking costs nothing
Your score is the furthest point to the right you have reached, not your current position, so stepping back to line up a jump costs nothing and standing still does. That makes it safe to stop on a wide platform, read the next two, and walk forward again. Never expect the number to follow you backwards.
Platforms only catch from above
Jumping up into the underside of a platform does nothing, because only a downward crossing of its top surface counts as a landing. So a platform above your head is not something to jump up to. Step off the edge beside it and let yourself come down onto it, which keeps your second jump for the gap after.
Falling is far more forgiving
A rise is only ever about three fifths of your jump height, but a drop is allowed one and a half times it, so the tolerance is far wider downwards. Where two platforms are both reachable, take the lower one. It keeps the landing short and predictable, which is where the second jump still has something to fix.
Platform Hop — Frequently Asked Questions
Can I get a gap that is impossible to clear?
No. Gaps and height differences are worked out from your jump height and jump distance with a margin, every time a platform is generated. So you can miss a jump through timing, but you cannot meet one that cannot be made.
Why did I pass through a platform instead of landing on it?
Because you were moving upwards into it. Platforms are one-way — they only catch you when you are coming down onto them. That is deliberate, and it is what lets you jump up through an overhang.
How many jumps do I get?
Two per time in the air: one from the platform and one more before you land. Touching down resets them.
What happens if I fall?
The run ends and your distance is your result. There is no life counter and nothing to lose but the run.
