Trailer
Thirty seconds of real play, captured from the live game build: tumbles and growing Bats, a Big Bite, then an Overtime Shift from 21:00 past midnight that ends in a Bloody Win.
See the top of the range. A real 25,000× Blood Moon Shift from the game's published maths, captured from the live game build.
Features
-
Bat Wilds that grow
A Bat counts as every paying symbol and never leaves in a tumble. It lands at ×1 and gains +1 for every tumble it stays. The chain's win is multiplied by the sum of all Bats: they add up, not multiply.
-
Vlado's Bite
In the base game, at random: when a chain ends with a win and at least one Bat, Vlado bites the board and every Bat doubles before the multiplier pays.
-
Night Owl
Play at 2× the bet for twice the chance of the Shift: free spins come 1 in 160 spins instead of 1 in 320, at the same 96.50% RTP.
-
25,000× in every mode
The same cap in the base game, Night Owl and all three buys. A round ends the moment it reaches 25,000× the bet.
The Graveyard Shift
Free spins play as one night: 10 spins, one an hour from 21:00 to 07:00. Bats stay where they land for the whole night and keep growing. Three Coffins during the Shift add 5 more spins, and the clock runs into overtime.
