Does it keep earning while I'm away?

It does. Your helpers earn Jewels passively, and you'll collect capped offline earnings when you return.

How do I earn faster?

Buy more buildings, purchase Boosts, and ascend to bank Royal Seals — each one permanently multiplies your output.

What does ascending (prestige) do?

Ascending resets your Jewels and buildings but grants Royal Seals that boost every future run, so you grow much faster.

Can I play on my phone?

Yes, it's fully touch-friendly and works on phones, tablets and desktops with one-tap controls.

Is my progress saved?

Your progress saves automatically in your browser, so you can close the tab and pick up right where you left off.

👆 Crown Jewel Vault

📖 View Web Story

Crown Jewel Vault drops you into a velvet-lined royal treasury and dares you to build the most regal jewels empire on the web. It all starts with a single tap on the vault: each press mints a little Jewels, and Court jewelers polish crown jewels that multiply behind a dozen locked doors.Spend what you earn to hire helpers like Little Jewelers, Busy Jewelers and eventually Cosmic Jewelers. They keep working even after you stop tapping, so your Jewels ticks up every single second — close the tab and you'll come back to a tidy pile of offline earnings. Stack boosts such as the "vault Festival" to multiply everything, then chase achievements that hand you a permanent edge.When growth slows, ascend to bank Royal Seals: each one you hold quietly supercharges all future runs, turning a slow start into an avalanche. It is built to play itself while you watch the counters climb, and it runs instantly in your browser on phone, tablet or desktop — no download, no sign-up. Fire up Crown Jewel Vault, find your rhythm, and see how big an empire jewels can buy.
