REX Stampede Slot by ELK Studios

Stampede: The Row-Wide Symbol Transformer

REX Stampede is a 5-reel, 4-row all-ways slot starting with 1,024 ways. The game centers on a feature that doesn't appear much elsewhere: two Stampede symbols landing on the same row trigger the Stampede Feature, which transforms every payout symbol between them into a T-Rex - the highest-paying symbol on the paytable. In base mode those become standard T-Rex. In the bonus, they become Golden T-Rex tokens. That distinction matters.

Any payout symbol can appear stacked on any reel, stacking size indicated by a number on the symbol itself. A stacked position counts as multiple symbol instances in that reel column. Combined with the all-ways payout structure, a full-column stack of one symbol type creates dense coverage for that symbol across multiple rows.

Multiplier Wilds: Guaranteed in Bonus Mode

Wilds substitute for all standard symbols. When a wild contributes to a win in the base game, it may reveal a multiplier of x2, x3, or x5. In the bonus game, that multiplier always reveals - every wild that contributes to a win becomes a Multiplier Wild. Multiple multiplier wilds in a single win stack multiplicatively.

Free Spins: Golden T-Rex Collection and Reel Expansion

Three bonus scatter symbols trigger 6 free spins. Four scatters award 12, five award 18. The defining mechanic of the bonus is reel expansion through Golden T-Rex collection. Collect 3 Golden T-Rex tokens on the same reel (reels 2 through 5) and that reel expands from 4 rows to 6. The expansion also converts one high-value symbol type to T-Rex on all reels for the rest of the bonus, and awards 1 additional free spin.

With all 4 expandable reels at 6 rows, the grid reaches 5,184 ways to win. Every expansion also concentrates T-Rex symbols further across the reels - symbols already converted in earlier expansions remain T-Rex. The last expansion, by definition, turns the final remaining high-value type into T-Rex as well. What begins as a paytable with 5 distinct high symbols gradually collapses into a single-symbol grid.

Reel 1 also collects Golden T-Rex, but expansion doesn't apply there - it awards 1 free spin and the token transforms to a regular T-Rex.

Super Bonus: Stampede on Every Spin

The Super Bonus X-iter buy costs 500x bet and guarantees that the Stampede Feature triggers on every single free spin. Every spin begins with the row-wide symbol transformation. Combined with wilds that always show multipliers in bonus mode, and the progressive T-Rex accumulation from reel expansions, each spin has maximum symbol compression toward the highest-paying type from the start. Max win: 25,000x. Hit frequency: 22.7%. RTP: 94%, single tier across all modes.
