RTP OPEN VAULT by Fa Chai Gaming is a casino slot built around an exotic treasure-vault theme. The game uses chest symbols that can connect with any symbol before revealing a random result, creating winning lines that may trigger rising multipliers during play.
In the free game feature, chest multipliers are assigned randomly at the start and do not reset the initial stacking multiplier, allowing wins to build through the round. This structure is designed to reach high multiplier levels, with a stated maximum of 10000x.
The demo version lets players play for free and practice before playing for real money. It is suited to users who want to review the slot mechanics, special symbol behaviour and bonus round format before staking funds.
