King 1x1x1x1

Every guide that mentions this boss mentions only its name. Here is the fight, read off recordings frame by frame.

You do not reach it. It arrives.

The run screen carries a permanent NEXT BOSS IN timer. When it hits zero, a green broadcast reads “1x1x1x1 is coming! Press ATTACK to join the battle.” and an ATTACK button appears. After a kill the timer resets to just under an hour, so the cycle is roughly hourly and it is the same for everyone on the server.

This is why “which wave is the boss on” has no answer — the game has no waves.

Dying opens a REVIVE? prompt with about twenty seconds on it, and reviving in the boss fight is a paid action costing 24 Robux. You can also just leave.

A naming trap

In the game the boss is called 1x1x1x1. The word King appears only in the Roblox badge, You defeated the King 1x1x1x1. If you search for the longer name expecting to find it on a health bar, you will not. Every site that writes about this boss uses the badge name; none of them mentions the difference.

How many actually beat it

How it is countedResultWhere it comes from

None is wrong. Roblox computes rarity over a recent window; the badge ratio counts everyone who ever played. A site quoting one figure with no method attached has not told you which.

Still not established

The tokens it drops are spent in the event shop.
