How it plays
Book of 99 is a slot from Relax Gaming in which collecting books in the Base Game triggers free spins and a character chosen at random gains expanding abilities in the Free Spins round. This page covers only the rules and figures that are officially published and offers no way to win.
Collecting books in the Base Game triggers free spins, an added route alongside the usual symbol trigger.
One of the warriors is chosen at random before the Bonus Round begins.
In the Free Spins round the chosen character gains expanding abilities and can grow to fill the whole reel.
Landing enough book symbols in the Bonus Round re-triggers the free spins.
Every round is random and earlier results have no effect on the next one. This site gives no betting advice.
