$Y Premium
The premium parts of Yuvin's Test Services — paid for with Y-Coins you earn by playing. No wallet. No card. Just play.
Found a launch code? Five letters — put it in here. the codes are explained on the home screen.
What your Y-Coins unlock
Premium is bought with coins, kept with love, and powered entirely by playing.
YuvinOS Desktop
The real desktop app for Mac, Windows and Linux — YuvinOS as a program you install, not a browser tab. It keeps itself up to date, and it is yours for good: when the browser YuvinOS retires on 30 November 2026, this one carries on.
YuvinOS: 50 more days
YuvinOS retires on 30 November 2026 — but Premium members with an account keep using it for 50 extra days after retirement day. The final goodbye, extended.
Premium tile themes
Repaint the whole home screen in one colour — Apple Red, Orange Citrus, Flash Yellow, Neon Green, Navy Blue or Lushing Violet — and switch on liquid glass to make every tile translucent.
Gold member card
Your digital member card turns gold — collect it from the Membership page.
Profile flair
The letter P in Lushing Violet sits beside your name on your profile, so everyone can see you are Premium.
How to earn Y-Coins
Your balance lives in the $Y notch at the top right of every page. It only ever goes up by playing.
Beat a math boss — $Y 10
Ten correct answers in a row beats a boss. Each boss pays once a day — five bosses, five payouts.
New typing record — $Y 15
Beat your own best WPM in the Typing Speed Test. Every new personal record pays.
Share a creation — $Y 25
Post a picture or video you made in Make Your Own to the Community Gallery. A developer checks it, and the coins are yours. Once a day.
the golden rule
Y-Coins can NEVER be bought with real money. Not now, not ever. This has been the golden rule since the day this website was born — because this is a community-managed hangout, not a money-making company.
