Dragon Vault by Lodestone places five reels inside a medieval treasure chamber, with dragons, royal figures and coin-filled chests sharing the board. Ordinary spins pay through ten fixed paylines, while Coins and Collect symbols build toward Hold & Win. Mystery symbols give the reel stop an extra stage: their reveal can turn the result into a bonus trigger.
Quick take: Sticky Mysteries give the free spins a growing foothold in this dragon-themed coin collector.
Theme and Gameplay
Torchlit stone walls, shields and swords frame a compact five-by-three board. Start a spin and watch matching symbols form combinations from left to right. The king Wild substitutes for ordinary paying symbols, but it cannot replace Coins, Collects, Mysteries or Scatters.
Mysteries deserve a second look after the reels stop. They all reveal the same symbol, with Coins among the possible results. That means the initial arrangement is not always the finished outcome: a shared reveal can supply enough Coins to open Hold & Win.
Slot Features
Six or more Coins, counting Collect symbols, start Hold & Win. The triggering symbols stay in place and three respins begin. Each new Coin or Collect restores the counter to three, so a late arrival gives the remaining empty positions another chance to fill. The round ends when the counter reaches zero or the board fills, and the held values are totalled.
Collect adds another consideration beyond filling spaces. It gathers values from Coins or Collects that landed before it; within Hold & Win, it can award the sum of held coin values. Its contribution therefore depends on the treasure already present.
Three, four or five Scatters award ten, fifteen or twenty free spins. Mystery positions stay for the remaining spins and reveal a fresh common symbol each time. Three or more Scatters add five spins, while a qualifying six-coin result can open Hold & Win during the free-spin round.
Feature focus: A sticky Mystery preserves a position, not a fixed revealed symbol: its next reveal can change what that space contributes.
RTP and Win Potential
Dragon Vault lists 94.00% RTP and an 8,000x maximum win. The RTP describes a long-term average, while the ceiling is a limit rather than an expected result. Mini, Minor and Major coins can carry one, two or three times their tier award. Filling the Hold & Win board adds a 1,000x Grand award to the held values, giving the last empty spaces a separate prize significance.
My Thoughts On This Slot
The free spins give the Mystery mechanic a useful sense of continuity. A position can stay involved across several turns without producing the same symbol every time, so there is something concrete to follow beyond the spin counter. The possibility of revealing enough Coins also connects the free spins to the main cash feature.
There is more bookkeeping here than the ten-line layout first suggests. Reading a paying line, counting Coins and following a Collect serve different purposes. That suits someone who enjoys a familiar reel game developing into a held-board bonus, though anyone wanting every result settled at the first stop may find the extra reveal stage less appealing.
Final Take: Dragon Vault earns its character through Mysteries that keep familiar reel positions involved in the treasure chase.
