Tunnel Rush

🕹️How do you play Tunnel Rush online?

1. 1Hold the Left or Right arrow key (or A / D) to rotate your ship around the inside of the tunnel.
2. 2On a phone or tablet, hold the left or right half of the screen; slide your finger across the middle to flip direction instantly.
3. 3Every coloured slab on the tunnel wall is lethal — find the gap and line up with it before you arrive.
4. 4Collect gold shards for points, blue diamonds for slow-motion and magenta diamonds for overdrive.
5. 5Press Esc or P to pause, and R to restart the run at any time.
6. 6Pick a difficulty first: Easy for wide gaps and a gentle ramp, Insane for barely-fair speed.

📋What are the rules of Tunnel Rush?

• ▸One hit ends the run — there are no lives, shields or second chances.
• ▸Speed rises continuously toward the mode ceiling and never drops back on its own.
• ▸Clearing an obstacle adds to your combo; the multiplier climbs one step every 4 obstacles and caps at ×4.
• ▸The combo lapses if you go about three and a half seconds without clearing anything.
• ▸Passing within a hair of a slab counts as a close call: bonus points, a screen kick, and it keeps the combo alive.
• ▸Slow-motion drops you to just over half speed for a few seconds; overdrive doubles your score but speeds you up.
• ▸Score is distance-based and multiplied by your combo, so the safe line and the greedy line are rarely the same.
• ▸Each difficulty keeps its own high score in your browser.

💡What are the best tips for winning at Tunnel Rush?

• ★Look at the gap, not at your ship. Your hands will follow your eyes, and the ship is the one thing on screen that never moves.
• ★Take the shortest way round. If the opening is more than halfway across the tunnel, going the other direction is faster.
• ★Tap in short bursts rather than holding — the ship keeps a little momentum, and holding almost always overshoots.
• ★Deep obstacles like pillars and drums have to be entered correctly; there is no correcting once you are inside one, so commit early.
• ★Close calls are worth real points and keep the combo alive, so on Easy and Normal it pays to hug a wall deliberately.
• ★Grab overdrive only when the track ahead looks open — double score is worthless if the extra speed kills you two seconds later.
• ★If a run is getting away from you, a blue slow-motion pickup is often worth going out of your way for.

ℹ️What is Tunnel Rush?

Tunnel Rush belongs to a family of one-axis reflex games that goes back to the vector arcade era — you are not steering in two dimensions, you are rotating around a circle, and the entire skill of the genre lives in reading a gap and committing to it before the geometry arrives. This version is built from scratch for PapoGames on an HTML5 canvas with no game engine and no downloaded assets: the tunnel is a fourteen-facet tube projected with a single perspective term, the obstacles are angular arcs generated by ten hand-tuned pattern makers, and the audio is synthesised in the browser with Web Audio. The design decision that matters most is that spacing between patterns is measured in seconds of reaction time rather than in fixed distance. Because the run gets faster every second, a fixed gap would silently become unreadable and the game would end up unfair rather than hard, so difficulty instead comes from where it should: narrower openings, faster-spinning slabs, meaner shapes, and a tunnel that corkscrews and bends underneath you. The four modes are genuinely different games — Easy tops out around 44 units per second with generous four-facet openings, while Insane starts faster than Easy ever finishes and pushes toward 98 with gaps barely wider than your ship. Between them sit the two you will actually spend time in: Normal is the reference pace, and Hard is where the combo multiplier and the close-call bonus start to matter more than pure survival.
