Open Vault demo and official FA CHAI facts
Open Vault is a FA CHAI Megaways slot released in February 2026. The studio's public page lists a 96.5% RTP, high volatility and a 10,000x maximum win, then explains how special chests reveal symbols and build multipliers. These are published game facts, not a forecast for a demo or paid session.

Feature guide
How OPEN VAULT works
Connecting treasure chests
FA CHAI says special chests can connect with any symbol before revealing a random symbol. Read the current paytable for the exact connection and evaluation sequence.
Growing base multipliers
Winning connections can increase the multiplier attached to the chest sequence. A visible multiplier is a rules state, not evidence that another win is due.
Free-game chest values
The official description says chest multipliers are assigned at the start of the Free Game and can stack without resetting the initial multiplier. Confirm the current version's trigger and calculation in its information screen.
Maximum-win boundary
The provider publishes a 10,000x maximum. That is a ceiling in the rules, not an expected result, probability or session target.
Demo checklist
What to test before any real-money decision
- Confirm the current demo identifies Open Vault by FA CHAI and uses the Megaways format.
- Compare the information-screen RTP and volatility with the published 96.5% and high labels.
- Read how special chests reveal symbols and how multipliers carry into the Free Game.
- Use virtual credits only and verify any live operator availability as a separate step.
