Book of Africra
4ThePlayer's twist on the book slot. Instead of one random pick, gold coins fill six symbol pots above the reels — one per symbol. Fill a pot and that symbol turns active, set to grow and fill whole reels during Free Spins for scattered pays across all 10 lines. Fill more pots and more symbols expand together. 94% RTP (92% and 90% builds exist), high volatility, 7,500x max, plus two Buy Feature modes where allowed.
Symbol Pots & Expanding Free Spins
Ever played a "Book of" slot and wished you had a say in which symbol expands? That's the hook here. 4ThePlayer took the book format and swapped the single random pick for six symbol pots that sit above the 5x3 grid — one pot per reel symbol. At 94% RTP and 7,500x max win, the twist is that you help build the bonus yourself.
Here's how it works: gold coins land stuck to symbols on any spin and drop into the matching pot. Fill a pot and that symbol turns active. Any filled pot can trigger the Free Spins, and every active symbol grows to fill whole reels, paying across all 10 Lines wherever it lands. Coins keep falling in the bonus, so fresh pots complete mid-round and switch on more expanding symbols — that's the route to 7,500x. Two Buy Feature modes are on hand where the rules allow, including a Mega mode that opens with two active symbols.

Bonus Mechanics Explained
4 mechanics drive the 7,500x max win. Here's exactly how each one works.
Symbol Pots & Coin Collect
How to Trigger
Gold coins land attached to symbols on any base or bonus spin. Each coin drops into the pot for its matching symbol; fill a pot to activate that symbol.
What Happens
Six pots sit above the 5x3 grid, one for each reel symbol. When a symbol lands with a coin on it, that coin travels to the symbol's pot. Fill the pot and the symbol is flagged active, meaning it will expand during the free spins round. You can work several pots at once, and progress carries into the feature.
Multipliers
The pots carry no cash multiplier themselves. Their value is which symbols get activated. A filled premium pot is worth far more in free spins than a filled low-symbol pot, since premiums pay more when they expand across the reels.
Odds (est.)
Coins land fairly often, but completing a full pot in the base game takes a run of them. Most triggers come from grinding one pot close, then topping it off. High-volatility pacing means dry stretches between activations are normal.
Variants
Coins keep appearing inside the free spins too, so pots you didn't finish in the base game can complete mid-bonus and add more expanding symbols.
Strategy
Watch which pots sit closest to full. A near-full premium pot is the one worth chasing, since activating a top symbol before the bonus is what turns a flat round into a big one.

AfricRa Free Spins
How to Trigger
Fill one or more symbol pots. Any activated pot awards 10 free spins.
What Happens
Once a pot fills, you drop into 10 AfricRa Free Spins with that symbol active. Every activated symbol becomes an expanding symbol for the round. Retriggering an active pot during the feature adds 6 more spins, and fresh coins can activate additional pots as you play.
Multipliers
No flat multiplier on the spins. Payout scales with how many symbols are active and how high they pay. Several premium expansions on one spin is where the round earns its keep.
Odds (est.)
Base trigger frequency runs low, in line with the high-volatility model. Retriggers and mid-round pot fills are common enough to stretch a round well past 10 spins on a hot streak.
Variants
The number of active symbols entering the round depends on how many pots you filled first. Walk in with two or three full pots and the feature starts far stronger.
Strategy
Bank a buffer before you go chasing the bonus. The value swing between a one-symbol round and a four-symbol round is huge, so the goal is stacking pots, not just triggering.

Expanding Symbols
How to Trigger
Active only in free spins. Every symbol activated via its pot expands when it lands for a win.
What Happens
When an activated symbol lands across enough reels to form a paying combination, those reels fill top to bottom with that symbol. The expansion pays across all 10 lines regardless of exact position, so one reel of a premium can light up the whole board.
Multipliers
No separate multiplier. The lift comes from full-reel coverage across 10 lines, and from multiple symbols expanding on the same spin.
Odds (est.)
A single activated symbol expands a handful of times across a 10-spin round on average. Multiple active symbols expanding together is rarer and far more valuable.
Variants
The more pots you fill, the more symbols can expand at once, so late-round pot fills visibly raise the payout ceiling.
Strategy
Premiums matter most. A low symbol expanding across every line still pays little, so aim your pot-filling at the high-value symbols before the bonus starts.

| Coverage | Full reel |
| Pays | All 10 lines |
| Best Case | Multiple premiums |
| Trigger | Activated symbol wins |
Coin Progression
How to Trigger
Coins continue to land during free spins and feed the pots.
What Happens
The bonus isn't static. Coins keep dropping while you spin, filling pots you left unfinished. Each pot that completes activates another expanding symbol on the spot, so the number of expanding symbols can climb as the round goes.
Multipliers
Indirect. Each newly activated symbol adds another full-reel payout source, compounding the value of every later spin in the round.
Odds (est.)
Adding a second or third active symbol mid-bonus is uncommon but not rare. It's the main way rounds snowball toward the 7,500x cap.
Variants
Enter with partly filled pots and progression happens faster, since those near-full pots often tip over in the first few free spins.
Strategy
Don't judge a round by its opening spin. A bonus that starts with one active symbol can finish with four if the coins keep coming, so let it play out.
