Book of Truth

Open Book of Truth and you arrive at an Ancient Egypt temple at night, lit by burning braziers and framed by statues, flames, and gold. The reels sit under a starry sky with a heat-haze shimmer, while a dramatic soundtrack with strong Arabic vocals pushes the pace. You play on a 5-reel, 3-row grid built for that classic book-slot rhythm.

Before you spin, set your paylines from 1 to 10 and then set your stake, starting as low as 0.01 per spin and reaching 100 at the top end. Expect medium volatility, with a headline win cap of 15,000x. You may see an RTP listing of 96.33% in one ruleset, while another listing quotes 94%, so check the in-game info panel.

Keep an eye on the Book symbol because it matters in two ways: it substitutes as a wild for all regular paying symbols to complete line wins, and it also lands as the scatter that unlocks both bonus tiers. In the pay mix, notice the 10 to A card ranks for lower wins, plus premium icons like Anubis, Bastet, and Horus, topped by the adventurer, with premium payouts ranging from 75x to 500x.

Land 3 Book scatters to trigger 10 free spins and an instant 2x stake win, or hit 4 scatters for the same 10 spins with a 20x stake payout. Before the round starts, watch the game pick one regular symbol at random as the expanding symbol. During the feature, that chosen icon expands vertically when it helps form a win.

Notice how expanded symbols pay across all active lines regardless of adjacency, so you are not relying on neat left-to-right clusters. That is where multi-line payouts build, especially if a premium is chosen. Keep an eye on retriggers too: hitting 3 or more scatters during free spins awards an extra 10 spins while keeping the same expanding symbol, extending your chances on the same setup.

If you land 5 Book scatters, expect 10 True Free Spins plus an immediate 200x stake scatter win. The twist is simple but powerful: there is no single chosen symbol. Instead, all regular symbols become expanding for the entire feature, so every icon that lands can stretch to fill its reel before wins are calculated. This is the route to the biggest swings and the 15,000x ceiling.

Use the buy option when you want straight access to the bonus tiers. Standard Free Spins cost 89x your stake, while True Free Spins cost 536x your stake, with those prices assuming all 10 paylines are active. If you reduce the number of active paylines, the cost lowers proportionally. Treat it as a bankroll tool: buy standard for the classic expanding-symbol chase, buy True for the all-symbol expansion burst.
