Guides
Master the gravity-switching tunnel: when to rotate, when to jump, how to avoid the void, and how to turn short runs into personal bests. This guide is built for players who want more than button reminders — it is a full path from first fall to late-game scoring.
Start here if you are new. These four moves cover almost every early-game situation — and they remain the foundation when the tunnel gets fast.
Press Left/Right (or A/D) to spin around the tunnel walls. Any wall can become your floor — use this to sidestep gaps instead of jumping every hole.
Tap Space or Up to leap over missing tiles. Time it well: a single jump clears short gaps, but wide openings usually need a wall switch plus one clean leap.
Grab the glowing cells scattered across the tiles. Each one boosts your score on top of the distance you cover — when the path is safe.
The tunnel accelerates the further you run. Stay calm, read the pattern ahead, and push for a new personal best every session.
Do not try to play like a high-score grinder on day one. Level up the decision you make at every gap — then the scoreboard follows.
Your only job for the first dozen runs is to survive. Ignore perfect scores. Every time you see a gap, ask: can I rotate onto solid ground? Jump only when the answer is no. That single rule cuts most early deaths and builds the muscle memory the rest of the game depends on.
Once rotation feels natural, start treating the tunnel as four (or more) lanes wrapped into a tube. Pick a continuous wall early when a trench opens, and stay on it. Begin chaining rotate-then-jump on wider holes. Add power cells only when they lie on the lane you already chose.
Late-game speed punishes hesitation. Pre-decide your next two inputs while you still have calm tiles underfoot. Skip greedy cell detours. Use short recovery runs after a fall to re-lock timing, then go for a dedicated high-score attempt when your hands feel quiet again.
Once the controls feel natural, these habits separate casual runs from long tunnels. Read them once, then pick one habit to focus on for your next five attempts.
Most early deaths come from jumping every hole. Scan one wall ahead: if a gap sits on your current floor, a quick Left or Right often puts you on solid tiles without leaving the ground. Treat jump as the backup plan, not the default.
Speed ramps up over time, so reaction-only play stops working. Train yourself to read the pattern two or three tiles ahead and decide whether you will rotate or jump before you reach the gap. The decision should already be made when your explorer arrives.
The tunnel is a cylinder. When the floor collapses into a long trench, the left or right wall is often continuous. Commit early to that lane instead of hopping back and forth mid-gap — indecision is what drops you into the void.
Wide openings sometimes need both moves: rotate onto a wall that still has a short missing section, then jump once. Practicing that combo is the key to mid- and late-run survival when single tools are not enough.
Cells raise your score, but diving onto a crumbling strip for one pickup can end a long run. Grab them when they sit on your planned path; skip risky detours once the tunnel is fast. A living runner scores more than a greedy fall.
On keyboard, rest on A/D or the arrows and only tap jump when you must. On mobile, keep thumbs near Left/Right and use Jump sparingly — over-jumping is the most common habit to break, and it gets worse as speed climbs.
A short run still teaches the next pattern. Restart immediately, aim for one cleaner decision than last time, and treat each attempt as practice rather than a failed high-score grind. Momentum beats frustration.
Your first attempt after a break is usually rusty. Spend a minute surviving rather than hunting cells so your timing recalibrates before you push for a personal best. Pros warm up; casual players who skip it leave points on the table.
Most falls are not bad luck — they are habits. Fix these four and your average run length jumps before you touch a single “advanced” trick.
If your first instinct is always Space or Jump, you will land on broken tiles and wonder why rotation exists. Default to a wall switch; leap only when the new floor still has a gap.
Watching the tile under the explorer leaves no time to plan. Lift your eyes two or three segments ahead so rotate and jump decisions happen early, not in a panic.
A cell on a crumbling strip can erase a long run for a tiny bonus. Late-game rule: if collecting it costs a risky lane change, leave it.
Spamming Left/Right after a scare often rotates you off the only solid wall. One deliberate tap beats three frantic ones.
Use this whenever you sit down to beat a personal best. It is short on purpose — so you actually do it before diving into a score chase.
No cell hunting. Rotate first, jump second. Goal: die less, not score more.
When a trench appears, pick a wall early and stay. Practice one rotate-into-jump combo per run.
With timing warm, chase cells on your path and protect a long run. Restart quickly after falls; do not tilt into worse decisions.
