Transparent 25-Line Slot. Classic 5×5 mechanic. Win on 3, 4 or 5 matching symbols left-to-right on any of 25 enabled paylines. Wilds substitute for all symbols except scatters. Every symbol weight is shown on the right.
The Transparent 25-Line Slot is the reference implementation behind AI-slots.com. Five reels of five symbols each, 25 fixed paylines, wild and scatter mechanics. Everything you'd expect from a modern video slot, except nothing is hidden: the weight table and paytable on the right are the literal values the RNG and evaluator use.
For each enabled payline, we read one symbol per reel along the line's row indices, then count consecutive matching symbols starting from reel 1. Wilds substitute for any non-scatter. A scatter on reel 1 ends the line. The win multiplier comes from the paytable times the per-line bet.
