Book of the Egyptian Buffalo Slot by Zillion Games

Two different bonuses split this one down the middle, and they trigger in completely different ways. Three gold books, the Wild, kick off the Free Spins. So do three of the blue book scatters, the buffalo-headed special symbol. Either route drops you into the "Book of" round where a random symbol gets picked to expand across full reels, and here that expanding symbol keeps its accumulated positions active from spin to spin rather than starting fresh each time. A Multichance layer runs on top, widening how often the good landings hit.

The other path ignores the books entirely. Land six gold bonus coins and the Hold and Ring locks them in place while the empty cells respin. Every coin carries a printed cash value, and a Mystery coin can flip into any tier except the top one. When the respins dry up you collect the summed total of everything showing. There are four fixed prizes hanging in a row above the reels, the Mini, Minor and Major reachable through those Mystery reveals, and the Grand sitting at 1000x your bet, locked behind one demand: every single one of the 15 cells has to fill with a bonus coin. Nothing partial counts toward it.

The base game runs across 25 lines and throws in a Full Win Line pop-up whenever a payline connects all five positions, a small ceremony most line-pay slots skip. There's no way to buy either bonus, so both the book round and the coin round have to land on their own.

Visually it's a warm desert-temple build. A golden buffalo idol draped in a striped Egyptian headdress stands guard beside the reels, its horns curling out, and the symbols pair carved-stone card values in dusty blue against ornately framed animal-god heads: a jackal, a wolf, a lynx and the buffalo itself, each ringed in gold. Pyramids sit low on the dusk horizon behind it all. It's a familiar Egyptian dressing, buffalo swap aside, but the split between an accumulating book round and a full-grid coin chase gives it two very different things to aim for.
