Color Relay

Press Play on the title screen and the run starts immediately — no download, no account, no sign-in. Your runner begins in Cyan and the first twelve objects of Leg 1 have guide rails, so a wrong colour there only bounces you off instead of ending the run. A finger prompt appears at the third band, the first place a colour change is actually needed.

Get as far as you can while handing off as many matching chips as possible. Every band you pass drops the colour you are wearing into a five-slot pouch, and every sixth object is a relay post in one colour that pays out based on how many chips in your pouch match it. Points come from the handoff, not from surviving.

Passing a band pays 1 and a graze — slipping through in the last 60 ms — pays 5. At a relay post, the matching chips in your pouch are counted as n: 3 chips pay 90, 4 pay 160 and 5 pay 250, while 0 to 2 chips only pay 2 for each one. Two posts in a row at n=4 or better add 50 from the second post onward, and the pouch empties after every post.

Push n from 3 to 5 at the posts you can reach — that single jump is worth 160 points, which is 160 bands' worth of survival. The way to do it is to stay on the post colour through all five bands before the post, and to pay an extra step the moment a band pushes you off, so you are one step from the post colour rather than two.

You reached a band wearing a colour it does not accept, and that is the only way to lose. The result screen names which of four things happened: you did not tap in time, you tapped past the colour you needed, your shifter was still refilling because you borrowed the beat, or you were caught wearing the in-between colour of a double change.

The shifter ring around your runner has to refill before another change can start, and refilling takes about eight tenths of the gap between objects. One change per object is always affordable, but a second one in the same beat borrows time from the next. Tapping while it refills queues one step; a third tap is ignored and the ring shakes to say so.

Nothing ends — you lose the whole pouch and score zero at that post, then carry on with an empty pouch. Relay posts cost you money, woven bands cost you the run. That is why dropping a chip you cannot safely reach is usually the right call, and why there is always a survivable option no matter what the track throws at you.

Yes, and the phone is what it is designed for. The whole playfield is one big tap target, so it plays one-handed in portrait, and landscape is supported with the track flowing right to left and the HUD moving into a left-hand column. On a desktop browser you get the same phone-shaped playfield centred on screen with identical timings.

It is completely free with no ads anywhere — not before your first run, not between runs, not as a revive offer. There is nothing to buy, no currency and no paid continues. The game also makes no network requests at all while you play, so nothing about your session is sent anywhere.

Your best scores, totals, level, unlocked tracks and skins, daily streak and settings are stored in this browser on this device only. There is no account and no cloud save, so progress does not follow you to another device and clearing site data removes it. If your browser blocks storage, the game still plays and tells you once that nothing will be kept.

Relay is the endless mode with no finish line. Sprint gives you 60 seconds and treats the buzzer as an ending rather than a death, so your score stands. Daily Track is 40 relay posts generated from the date, identical for everyone that day, and finishing it is the closest thing this game has to winning. Leg 2 and Leg 3 starts unlock at level 3 and level 8.

Yes. Each of the three colours carries its own texture as well as its hue — Cyan is diagonal stripes, Magenta is dots and Amber is a solid outline — so every judgement can be made without relying on colour. The pause panel also has a high-contrast weave option that thickens those textures, plus reduced motion, sound and vibration switches, and the run reads its state aloud for screen readers.
