Scarab Slot Machine Advantage Play

Advantage play IGT's Scarab — the model 10-spin-cycle AP title. Wild Stays, Charges Then Pays mechanic with 5x4, 75-line gold-border lock-ins.

How Scarab Works

Scarab is an IGT video slot widely considered the model AP title for the 10-spin-cycle persistent-state structure. The base game uses a 5x4 reel set with 75 paylines, paying left to right only. The defining mechanic IGT calls 'Wild Stays, Charges Then Pays' — the game runs in 10-spin cycles, with scarab symbols that land getting a gold border around their position and locking in place for the cycle. On the 10th spin, all gold-bordered positions transform to wild and the screen scores.

The Scarab symbol acts as a blocker on the spin it lands — it doesn't pay on its own and prevents line wins through its position on that spin. But its value comes from the gold border that locks into place for future spins in the cycle. If a Scarab appears in a position that already has a gold border, nothing additional happens. Before spin 1 of a new cycle, all gold borders are erased and the screen resets to baseline.

The bonus is triggered by 3+ Bonus symbols and offers a volatility choice: 5 wilds with 15 free spins, 7 wilds with 10 free spins, or 10 wilds with 5 free spins. Bonus events typically pay 50x bet or higher when they hit. Multiple bet levels each track independent persistent state, and some configurations are multi-denomination, multiplying the count of independent persistent states the cabinet holds. Sequel Scarab Grand expands to a 5x6 reel set, and the IGT clone Diamond Mania uses the same fundamental engine.

Where the Advantage Comes From

The advantage on Scarab is the spin-count plus gold-border state visible on the cabinet. The spin counter at the bottom of the screen shows where the cabinet is in its 10-spin cycle. Gold borders on the reels mark positions that will turn wild on spin 10. Walking up to a cabinet showing several gold borders with multiple spins remaining captures the entire wild-conversion equity that fires on spin 10.

Reading the cabinet is exceptionally clean because the structure is finite. Spin 10 of 10 means the cycle just completed — starting now begins a fresh cycle with no advantage. Anything other than 10 of 10 with gold borders present is potentially a play. The Wizard of Odds threshold protocol is straightforward: after spin 1-4, take the cabinet with 2 wilds in the first 3 reels; after spin 5-9, take it with 3 wilds in the first 3 reels. Reels 1-3 carry more equity because the game pays left to right.

The 10-spin cycle structure makes Scarab one of the cleanest AP plays available because the bankroll commitment is explicitly bounded. A play picked up on spin 8 of 10 has at most 2 spins of additional commitment to reach the spin-10 wild conversion. That predictability is why Scarab is often the introduction game APs use for new players — the math is bounded and the read is simple. The trade-off is that Scarab plays are well-known and casinos in some markets have introduced countermeasures including barring known advantage players.

The actual bonus-frequency math, the column-weighted equity calculations, and the bankroll required for multi-cabinet capture rotation — that's what the courses are for.
