Free spins and the expanding symbol
In the real game the promotion is random. Here you can choose, to see what each symbol is actually worth over the round.
This is why two players describe the same bonus as either the best or the worst feature in slots. They drew different symbols.
The same build, at an operator licensed where you live.
Play Book of RaHow the bonus triggers
Three or more books anywhere on the reels in a single spin. They do not need to sit on a payline, and they do not need to be on adjacent reels.
Ten spins as standard
Three, four or five books all award ten free spins. More books do not mean more spins.
Plus a scatter payout
Three, four or five books pay 2x, 20x or 200x your total stake on top of triggering the round.
Then the promotion
Before the first free spin the game picks one symbol at random and promotes it for the whole round.
Retriggers
Three more books during the bonus adds another ten spins on top, keeping the same promoted symbol. Chains of retriggers are the single biggest source of record wins in this game.
A retrigger does not re-roll the promoted symbol. Drawing a card rank at the start and then retriggering three times extends a disappointing round, it does not rescue it.
What the bonus is worth
Which symbol gets promoted decides most of the round before you have played a spin of it. The explorer is worth roughly thirty times what the lowest card rank is worth over the same ten spins, and each of the six candidates is equally likely.
This is why two players can describe the same bonus round as either the best or the worst feature in slots. They are describing different random draws.

The brand is kept in the tracking label, so the reports show how many clicks land elsewhere. Set the offer URL in CASINOS (inc/data.php) to point a row at its own brand.

Every operator here has been confirmed to carry the genuine Greentube build and to hold a licence in the market shown. Payout speed and the licensed RTP setting are left blank because operators do not publish them — the help screen inside the game is the only authority for your session. We earn a fee when you sign up through a configured link, which does not change what is listed.
