II89 · PROVIDER GUIDES
Booongo often returns to a theme with a second game, and the follow-up rarely plays like the first. At ii89 online casino you can open four of these pairs, from Sun of Egypt to Sun of Egypt 3, and this page shows what changes between them before comparing all 16 BNG slots.
Booongo, which goes by the short name BNG, has an official list of 208 released games. For each it publishes the reel grid, the pay lines, the main features and any jackpot tiers. Those details show that a sequel is often a different game in a familiar costume. Of the 16 Booongo slots at ii89, eight form four pairs: two Egyptian games, two dragon games, two wolf games and two coin games.
Most of them are built on Hold and Win. When enough bonus symbols land, they lock in place and you get a set of respins, and every new bonus symbol that lands locks too and keeps the round alive. Respin counts, symbol values and how each jackpot tier is won differ by game, and each game's rules screen gives the exact figures.
On the surface nothing changes: both run 25 lines on 5×3 reels. The bonus is where they part ways.
Want one clear bonus to learn? Play the original. Want a second bonus stage and the top tier? Go to the third game.
Another pair on the same 25-line, 5×3 layout. Dragon Pearls gives you Hold and Win respins plus free spins with top symbols, carries a medium volatility rating and lists a 1,000x Grand. 15 Dragon Pearls lists a bonus game with two collect symbols instead, and its Grand is 5,000x the bet. The sequel also has the better agreed RTP, 95.71% against 95.01%.
The original dragon game, with a medium volatility rating agreed by review sites and a 1,000x Grand. You get two separate features to watch for, Hold and Win respins and free spins, so it is a good place to see how Booongo builds a standard bonus.
Open it straight after Dragon Pearls. The reels look alike, but the bonus game now has two collect symbols and the Grand jackpot is five times higher, at 5,000x the bet. The rules screen explains what the collect symbols do.
The sequel with the most added. Its two bonus stages, Bonus and Super Bonus, and its mystery symbols make it busier than the first Sun of Egypt, and its Royal tier of 10,000x the bet is shared only with Aztec Fire among the 16 games at ii89.
The wolf games share a 1,000x Grand jackpot and 25 lines, but not a screen. Black Wolf adds a fourth row, making a 5×4 grid, and lists a Boost feature with mystery jackpot symbols. Wolf Saga stays on 5×3 reels, uses a Boost symbol and adds giant symbols in its free spins. Black Wolf is agreed as medium volatility at 95.65%. Wolf Saga's agreed 96.06% is the highest RTP of all 16 Booongo games at ii89.
These are the two 3×3 games, and both are rated medium volatility. 3 Coins is the purist's version: five lines and classic Hold and Win respins started by three coins, with no jackpot tier in Booongo's data and an agreed RTP of 95.84%. Coin Volcano is built around Hold and Win, with volcano multipliers, an Ultra bonus game and a 500x Grand, the smallest top tier here. Its agreed RTP is 95.66%.
Not a numbered sequel, but a useful comparison. Aztec Sun is a classic 25-line, 5×3 game with Hold and Win respins, free spins and a 1,000x Grand. Aztec Fire moves to 20 lines on 5×4 reels, has a bonus board that unlocks rows up to 5×8 and lists a 10,000x Royal jackpot.
Tiger Jungle and Queen of the Sun share sticky wild free spins and a 5,000x Grand. Hit the Gold!, Gold Express and Magic Apple all list a 2,000x Grand; Gold Express is the only game with an agreed high volatility rating. Super Sticky Piggy lists no jackpot tier but has a jumping wild up to x10 in its free spins.
Grids, lines, features and jackpot tiers come from Booongo's official data. RTP and volatility are filled in only where at least two review sites agree; elsewhere the table says "Shown in game info", and the game's own info panel has the figure.

Within the pairs, the agreed RTP gaps are small. 15 Dragon Pearls beats the original Dragon Pearls by 0.70 points, Wolf Saga beats Black Wolf by 0.41 and 3 Coins edges Coin Volcano by 0.18. The first Sun of Egypt has no agreed figure, so only its sequel can be compared. RTP is a long-run average across a huge number of spins, so it cannot predict a session.
Booongo offers casinos several RTP settings for each game and each casino chooses one. That is why a title can show a different number elsewhere. ii89 runs every Booongo slot on its default setting, which is the highest available.
Use the provider filter to show Booongo games, or type a title into the search. Include the number when you search for a sequel, as originals and sequels sit close together in results. Some casino lobbies list a few of these games under 3 Oaks, so searching by the game's name is the most reliable route. Our 3 Oaks page covers that studio separately.
ii89 supports demo play, which suits this kind of comparison. Open the original on practice credits, trigger a bonus if you can, then open the sequel and do the same. Demo credits have no cash value. See how to start demo play for the steps.

Both use 25 lines on 5×3 reels. Sun of Egypt pairs Hold and Win respins with free spins and lists a 1,000x Grand jackpot. Sun of Egypt 3 adds Bonus and Super Bonus games with mystery symbols and lists a Royal jackpot of 10,000x the bet.
It is a separate game on the same 5×3, 25-line layout. Dragon Pearls has free spins with top symbols and a 1,000x Grand. 15 Dragon Pearls has a bonus game with two collect symbols and a 5,000x Grand.
Black Wolf if you like a taller 5×4 screen and a medium volatility rating. Wolf Saga if you prefer 5×3 reels, giant symbols in free spins and the highest agreed RTP of the 16, at 96.06%.

No. The 10,000x Royal is a jackpot prize; Booongo does not publish a max win for any game on this page.
