Boo, from Big Time Gaming, haunts a 4×4 grid offering 256 ways to win amid a misty graveyard setting. This online slots entry features cascading reactions that clear winning symbols, Rainbow Wilds carrying up to ×4 multipliers, and Pumpkin Scatters that trigger a Free Spins round where sticky multipliers accumulate per position. With high volatility and a maximum win potential reaching 47,050× your stake, it offers a thrilling spooky-season spin.
Set your stake and spin to form matching combinations across adjacent reels. Whenever you win, the cascading Reaction mechanic removes those symbols and fills the grid with ghosts, wilds or scatters, allowing more wins. Wilds land on reels 2–4 in rainbow form and may reveal multipliers up to ×4, which apply to winning lines. Three or more Pumpkin Scatters launch the Free Spins round with 12 spins and guarantee each grid position begins with a persistent multiplier that grows—by +1 to +3—whenever ghosts or wilds form part of a win, and retriggers add extra spins too.
The maximum bet a player can make when playing a typical round of Boo is £10. This amount strikes the right balance for both low-stakes players as well as those who prefer taking more risks.
Yes, Boo can indeed be played on a mobile phone as well as other devices with access to a secure web browser, ensuring access to all your favorite games wherever you feel like playing.
Boo has a Return-to-Player rate (frequently known as RTP) of 96.54%. This generous RTP gives players the assurance that the next big win is never more than a few rounds of gameplay away.
