Wilds, multipliers & mystery (CellPin)

Wild and mystery mechanics built on the engine CellPin primitive: pin once, the engine handles the overlay, countdown and cleanup.

Expanding wild#

Wild lands and the whole reel turns wild for N spins, then auto-expires when the turn counter hits zero.

Sticky wild (CellPin)#

A sticky wild on the primitive: pin on land with turns: N, the engine overlays it and counts down. no ghost sprites, no manual grid injection.

Walking wild (movePin)#

A wild migrates one reel left each spin via reelSet.movePin(), with flight hooks for Spine run animations.

Gotcha: walk pins sequentially with await, never Promise.all. two pins moving to the same cell throws.

Multiplier wild#

Each wild carries a per-instance multiplier in its pin payload; an xN badge overlays the cell and win eval reads pin.payload.multiplier.

Positional multiplier cells#

Specific cells carry a multiplier; any symbol that lands there boosts the win passing through.

Mystery reveal (CellPin)#

Mystery symbols land, then all reveal to the same random class via 'eval' pins that auto-clear on the next spin.

Spine mystery reveal#

Mystery bushes land and burst; an overlay Spine plays the reveal while activate() swaps the cell underneath, so the hand-off is seamless.

Expanding wild on a horizontal set#

The same expand-the-whole-reel pin on .orientation('horizontal'). Pins are index space, so the code is unchanged; the expansion just paints a screen row instead of a column.

Sticky wilds on a roll-up respin#

A .direction('reverse') set: the reels travel upward through three respins while pinned wilds hold their cells, and new wilds picked up on the way stick too.

Gotcha: pin coordinates stay geometric. cell 0 is the top cell whichever edge the strip feeds from.

Sticky-win respin#

Winners lock for N respins while the rest of the grid spins; re-pinning a winning cell refreshes its counter, so a new win resets the window.
