Rainbow Reels is a Pragmatic Play 5 x 3 cascade slot where winning symbols reveal seven deeper layers, and final-layer bonus wilds can survive up to thirteen winning uses.

Seven hidden layers turn each winning cell into progression, but a final-layer wild still needs payable line contact before one of its lives is used.

Layout version

This review covers the three-row layout with 20 paylines.
Another verified version adds one reel row and uses 40 paylines.

Wins Reveal Deeper Layers

Winning combinations on the 5 x 3 grid are evaluated across twenty fixed paylines. Symbols involved in a win are removed, exposing the next icon layer beneath those positions, and the result continues while the newly revealed layout creates another payable combination.

Each position contains a progression of seven layers. Successive wins at the same cells uncover deeper states, so cascade value depends on where winning symbols overlap rather than on a separate multiplier attached to every removal.

A set of three scatters opens the bonus. Revealing the seventh layer there creates a wild that can participate in up to thirteen winning combinations before removal, while several final-layer wilds can cover more of the board and Bonus Buy provides direct entry.

Layer Persistence Effects

  • Layer reveal: Winning cells expose the next symbol state underneath.
  • Cascade: Newly uncovered symbols can create another line result.
  • Final layer: Complete bonus progress converts that position into wild.
  • Wild lives: A created wild can support up to thirteen wins.
  • Board spread: Several mature positions can expand total wild coverage.
  • Bonus buy: Direct entry skips natural scatters at added cost.

Wild Durability and Payouts

Payout value builds where repeated line wins revisit the same grid positions and expose deeper layers. A broad first cascade is not sufficient by itself; later symbols must continue forming payable lines across cells with advanced progression.

Bonus wilds concentrate value through durability rather than a fixed cash amount. Each can support up to thirteen winning combinations, but a life contributes only when the wild participates in a valid line before its remaining count reaches zero.

Multiple final-layer wilds can increase board coverage, yet they do not guarantee the x5,000 ceiling. Bonus Buy changes the cost of reaching the round, while seven-layer progression and subsequent line contact still determine whether persistent wilds produce value.

Player fit and limitations

  • Layer tracking: Suits players who follow persistent cell-by-cell progression.
  • Cascade flow: Suits players who prefer consecutive wins within one result.
  • Seven-layer gate: A bonus wild requires complete position progression.
  • Wild expiry: Each mature wild disappears after thirteen winning uses.
Cascade purchase cost

Direct bonus entry concentrates spend before any cascade result appears.
