Base Game Mechanics
The slot uses a standard 5-reel, 3-row layout with 10 fixed paylines paying left to right. High-value symbols include the golden fishing hook (paying 200x for five-of-a-kind), pelican, fishing rod, and Romanian backpack. Card symbols 10 through Ace make up the lower pays.
Money fish symbols land randomly, each displaying a value between 0.2x and 1,000x your bet. Occasionally after a base game spin, a random collection event triggers where all visible money fish values are collected and paid with a random multiplier between 1x and 50x.
Free Spins Trigger & Modifiers
Landing three or more Baboi scatter symbols anywhere on the reels triggers the special round with 10 free spins. Four scatters grant one random modifier, whilst five scatters award two modifiers.
- Extra Free Spins: Reveal objects to add 1, 2, or 3 additional spins (maximum 6 extra)
- Guaranteed Fish: Ensure 1-3 money symbols appear on every single free spin
- Pre-collected Wilds: Start the round with up to 3 Fisherman Wilds already counted toward retriggering
- Small Fish Elimination: Remove 2x and 5x value fish from the pool, leaving only higher values
You pick objects to reveal modifiers until you uncover a boot, which ends selection and starts the free spins with all accumulated bonuses active.
Free Spins Collection System
During free spins, Fisherman Wild symbols appear on all reels and substitute for everything except Baboi scatters and money fish. Each Wild that lands collects the combined value of all money fish visible on that spin, multiplied by the current level multiplier.
All Fisherman Wilds remain collected until the round ends. Every fourth Wild collected retriggers the feature with 10 additional spins and increases the multiplier:
- Level 1: 1x multiplier (initial 10 spins)
- Level 2: 2x multiplier (after 4 Wilds collected)
- Level 3: 3x multiplier (after 8 Wilds)
- Level 4: 10x multiplier (after 12 Wilds)
- Levels 5-8: Increase to 20x, 30x, 40x, and 50x respectively
Random hooks may pull reels to bring Wilds or money fish onto the screen when one type is present without the other. The feature cannot retrigger beyond level 8.
Maximum Win & RTP
The slot caps wins at 10,000x your total bet. If this limit is reached during free spins, the round ends immediately, you're paid the maximum win, and any remaining spins are forfeited.
Big Bass Baboiu' din Delta operates at 96.07% RTP in both standard play and buy bonus mode. Activating the ante bet (which increases your stake to 1.5x) adjusts RTP slightly to 96.06%. The game carries maximum volatility (5 out of 5), meaning wins arrive less frequently but with potential for substantial payouts when they do land.
Symbols & Payouts
At the maximum bet of £250, five golden hooks pay £50,000, whilst five pelicans award £25,000. The fishing rod and backpack both pay £12,500 for a full line. Card symbols range from £1,250 to £2,500 for five-of-a-kind.
The golden hook is unique as the only symbol paying for just two on a line (£125 at max bet). The Baboi scatter doesn't pay directly but unlocks the entire free spins collection feature. Money fish values scale with your bet—at £1 wagered, a 500x fish awards £500.
