Played All Summer Instead of Studying? Prove It: Tunnel Keeper Is Live, and 50 Winners Get a Year of Le VPN

School is back, the campus Wi-Fi survival guides are making their annual rounds, and we have a question for everyone who spent the summer insisting that gaming counts as a skill: prove it.

Today Le VPN launches Tunnel Keeper, a free browser game with a real prize behind it. It is Snake, one of the most played mobile games ever, rebuilt the way we always wanted it: on a rotating 3D pixel globe, where the snake is a VPN tunnel and every piece of food is a real city from our server network. Connect 15 cities in one unbroken run and you win a code for a full year of Le VPN. There are exactly 50 codes. When they are gone, they are gone.

What Is Tunnel Keeper?

Tunnel Keeper is a snake game played on the surface of a chunky, voxel-style pixel Earth. Your snake glides across oceans and continents, and the globe turns under it as it moves. Scattered across the planet are 30 glowing beacons: real cities and countries from Le VPN’s network, which in the real world spans servers in 100+ locations.

One city is lit up as your target at a time. Reach it and it “connects”: the beacon flares, a thin tunnel line links it to the cities you have already collected, and the next target lights up somewhere else on the planet. Eat New York, chase Paris, swing down to South Africa, sprint across to Singapore. Your growing network is drawn right onto the globe behind you, which is exactly the point: the snake is your tunnel, and the game is the Le VPN map coming alive one connection at a time.

Connect 15 cities in a single run and you have beaten it. The victory screen asks for an email address, and a unique promo code for one year of Le VPN lands in your inbox. That is a full Le VPN subscription: apps for every device, servers in 100+ locations, and up to 10 simultaneous connections.

Fair Warning: This Game Does Not Like You

Here is the part we are strangely proud of. Tunnel Keeper is hard. Not retro-hard as an aesthetic, actually hard.

The snake speeds up with every few cities you connect. Each city makes you longer, and by the twelfth connection your own tail is the most dangerous thing on the planet. Obstacles spawn on the globe as you progress, styled as the things a VPN deals with in real life: tracker eyes, ad blocks, firewall bricks. Touch one and you are done.

And then there is the camera. On a sphere there is no fixed “up”, so the camera follows your snake around the curve of the world, which means the horizon is always rolling and your next target is frequently somewhere behind the planet. Some of what you will swear is broken is placed there on purpose. During development we argued more than once about whether the whole thing was too cruel to release, and briefly considered shelving it. It shipped anyway, camera and all.

The game is tuned so that most first-time players die somewhere around city 5 to 8, and so that players who put in ten or twenty minutes of practice start reaching the win screen. That is the tuning we wanted: a prize worth 1 year of VPN should not fall out of the game because you wandered into it. If you grew up on a Nokia keypad, consider this your rematch. If you spent this summer speedrunning instead of studying, here is the exam.

The Prize: 50 Codes, One Year of Le VPN Each

The rules are short:

• Win condition: connect 15 cities in one run.
• Prize: a unique code for 1 year of Le VPN, sent by email.
• Pool: 50 codes total, one per email address, first come first served.
• Deadline: the campaign ends on 31 October 2026, or the moment the 50th code is claimed, whichever comes first. Full details are in the terms and conditions.

After the codes run out, the game stays online for bragging rights. The full 30-city run remains available as a perfect-game goal for the kind of person who needs to see every beacon lit.

Yes, We Know Some of You Will Open DevTools

A browser game that hands out year-long subscriptions gets attacked by bored programmers within the hour, and we would honestly be a little disappointed if it did not. So here is what you are up against.

Tunnel Keeper’s game logic is deterministic. When you start a run, the server hands your browser a signed seed that decides the order of the cities and where every obstacle appears. While you play, the game records nothing but your steering inputs. When you claim a win, your browser sends that input log back, and the server replays your entire game, move for move, against the same seed. If the replay does not genuinely reach 15 cities, if the seed is stale, or if your “fingers” show timing no human hand produces, the win is rejected. Edited scores do not exist, because the score is never sent, only the moves that would earn it.

In other words, the only working cheat is being good at Snake. We have simply automated the part where your friends do not believe you.

A Love Letter to the Best Commute Game Ever Made

Snake deserves the tribute. The version everyone remembers was written by Nokia engineer Taneli Armanto and shipped on the Nokia 6110 in 1998, steered with a keypad on a screen the size of a postage stamp. In the years that followed it became available on more than 350 million phones, played in classrooms, bus stops and meetings on every continent.

Tunnel Keeper keeps the sacred parts: relative left-and-right steering, the tail that punishes greed, the one-more-try loop that ate a generation’s battery life. It changes exactly one thing. The original Snake lived on a flat screen with wrap-around edges, and ours lives on an actual planet, because that is where a VPN’s world is: gamers, travelers and remote workers hopping between real cities on a real map. The wrap-around is still there. It is just called geography now.

How to Play (and Actually Win)

Go to tunnel-keeper.le-vpn.com on anything with a screen. On desktop, steer with the arrow keys or A and D. On a phone, use the two on-screen steering buttons and drag the globe to look around. There is no account, no download and no tutorial worth skipping; a run starts in seconds and retry is instant.

Three tips from the people who built it and still lose regularly:

• Drag the globe. You can rotate the camera freely while playing. Players who scout the route to the next city before committing live noticeably longer than players who chase blindly.
• Respect the speed ramp. The early cities are a warm-up. Plan your turns wide from city 8 onward, because your tail will be everywhere and the ticks come fast.
• Use the whole planet. There are no walls anywhere. Some of the best escape routes go over the poles, where pursuing your target in a straight line would kill you.

Fifty codes. One planet. School has officially started, and this is the one test this term where playing all summer counts as revision. Show us what you learned.
