Mystic Catrin by FBM gives its Mexican-themed reels a feature built around Wilds that have not paid yet. The board has five reels, three rows and twenty fixed paylines. A losing result containing a Wild can open an extra spin, while the bonus lets unused Wild positions develop into multipliers.
Quick take: Watch what happens to a Wild after the reels stop. In Free Spins, missing a win can leave it in place for another chance and a possible upgrade.
Theme and Gameplay
The twenty line patterns stay active as you choose a stake and spin. A Wild can appear anywhere on the five reels, helping ordinary symbols form a paying combination. Scatters are the exception: a Wild cannot replace one to complete the feature trigger.
There are two different reasons to follow a Wild position. It might help the current result pay, or it might survive into an extra spin. That second possibility gives a stopped screen something more to show than the immediate line awards.
Slot Features
An ordinary spin with one or more Wilds and no win awards one Wild Respin. The triggering Wilds lock for that extra spin, then leave the board afterward whether the result pays or not. The feature provides one additional opportunity rather than keeping a collection across ordinary spins.
Three Scatters on reels one, three and five open ten Free Spins. Here, a Wild that does not take part in a win can stay in its position for subsequent spins. A new Wild landing on that occupied spot upgrades its value through 1x, 2x, 3x and 5x.
Those values affect combinations that include the relevant Wild. If several multiplier Wilds contribute to the same combination, their numbers add together. Once a sticky Wild helps produce a win, the entire sticky collection clears before the next spin. A single Scatter adds one Free Spin during the round. The feature menu also offers direct Free Spin purchase.
Feature focus: A bigger number is useful only when its Wild joins a paying combination. After a winning contribution, check the whole board again: all sticky positions clear, including those outside that win.
RTP and Win Potential
Mystic Catrin has a 95.56% RTP and a maximum win of 2,000x. A full screen of Wilds in the main game pays a separate 400x. The Wild upgrade sequence stops at 5x per position, while several qualifying positions can combine their multipliers within the same win.
My Thoughts On This Slot
The reset after a Wild-assisted win is what shapes this bonus for me. Building an upgraded position gives the round an objective to follow, but using it also clears the other sticky positions. It creates a repeating pattern of collecting, upgrading and starting over, rather than a board that steadily fills until the last spin.
Twenty fixed lines make the ordinary game familiar enough to keep that rule in focus. The main adjustment is remembering that an impressive-looking multiplier still needs the right combination around it. This should appeal to someone who likes tracking a few developing positions; a player who wants every collected Wild to remain until the feature ends may find the clearing rule less satisfying.
Final Take: A twenty-line Mexican-themed slot where unused Wilds earn extra chances and bonus multipliers build until a winning contribution clears the collection.
