About Treasure Tunnel
Treasure Tunnel gives you exactly two directions and a corridor that will not stay still. The channel wanders on a smooth curve and tightens steadily as the run progresses, down to a floor width below which it never goes. The main coin trail runs along the centre line, so following the coins is the same act as staying alive. What makes it a game rather than an exercise is the branch lines: higher-value bonus tokens placed out near the walls, in a gap that is still narrowing. Taking them is a genuine gamble.
How to play
- Steer up and down only. Forward motion is automatic and accelerates over time.
- The corridor walls are lethal. Scraping either one ends the run.
- The coin trail runs along the centre of the safe channel. Following it keeps you alive.
- Branch lines of bonus tokens appear near the walls. They are worth more and are considerably riskier.
- The channel narrows as the run goes on but never below a fixed minimum.
How to collect coins in Treasure Tunnel
The centre trail is continuous, so you collect from it without doing anything special beyond steering well. Branch tokens sit about a third of the channel width off-centre, which means taking one puts you close enough to a wall that a wander in the wrong direction will end the run. Gems appear on the centre line roughly one pickup in twelve.

Every coin here is virtual. Coins, gems, tokens and treasure in this game are in-game collectibles with a point value inside the game and no monetary value of any kind. They cannot be bought, sold, exchanged or withdrawn, and this site has no currency system.
Power-ups in Treasure Tunnel
Power-ups appear during a run and activate the moment you touch one. None of them can be bought, none carry over between runs, and collecting one you already have refreshes its duration rather than stacking it.
-
MagnetPulls nearby coins, tokens and gems toward you for seven seconds. Treasure chests are never affected.
-
ShieldAbsorbs one hit and then breaks. It saves the run, but the combo streak still resets.
-
Double ValueDoubles the value of every collectible for eight seconds. Applies before the combo multiplier, so the two stack.
How scoring works
Coins are worth 12 points before multipliers, tokens 60, and you earn a point per metre. Speed climbs continuously, so the metre rate quietly becomes the larger part of a long run's score.
Points for each pickup are its base value, multiplied by any active double-value effect, multiplied by your current combo tier. Distance and completion bonuses are awarded flat, outside that chain.
The combo system
The combo window is 2.0 seconds with the highest tier thresholds of any endless game, at 7, 16, 28, 44 and 62. The centre trail is dense enough that those are reachable, which is the reward for holding a clean line.
Difficulty
Hard
Hard. Only two directions sounds simple, but the corridor's drift means you are constantly correcting, and the narrowing makes late-run mistakes far less survivable than early ones.
Tips for a better score
- Steer toward the centre of the channel, not toward the next coin. The coins are already on the centre line.
- Particles spray off your collector when you are close to a wall. That is a warning, and it is the only one you get.
- Take branch tokens early in a run when the channel is wide. After about ninety seconds they are rarely worth it.
- The shield is worth more than the magnet here, because a wall scrape is the only way the run ends.
- When the tunnel curves sharply, move to the inside of the curve rather than following the trail exactly. It gives you more margin.

Treasure Tunnel — frequently asked questions
Does the tunnel eventually become impossible?
No. The channel has a hard minimum width of twenty percent of the screen height and never goes below it, no matter how long the run lasts.
Are the branch lines worth taking?
Early in a run, usually yes — a token is worth five coins. Late in a run, when the channel is near its minimum, generally not.
Is the treasure real?
No. All the collectibles here are virtual in-game items worth points inside the game only.
Can I slow down?
No. Forward speed is automatic and increases with the difficulty ramp. Steering is your only control.
