Filter by game type and find the slots that suit you best
Slots are, without a doubt, the most popular category at b777 — and for good reason. They combine straightforward rules, incredible visual variety, and the real possibility of multiplying your balance several times over in a single spin. At b777 you have access to over 1,200 titles, from classic three-reel games to Megaways slots with hundreds of thousands of ways to win.
Slots, also known as slot machines or pokies, are reel-based games that spin and land on symbol combinations. When the right symbols line up on the paylines, you win. At b777, all slots use an RNG — random number generator — certified by independent audit. This ensures every spin is completely random and fair, with no interference from the platform.
RTP (Return to Player) is the average percentage a slot pays back over many rounds. A slot with 96% RTP returns, on average, R$ 96.00 for every R$ 100.00 wagered over time. At b777, the RTP of each game is visible before you start playing — the transparency you deserve.
Volatility determines how often a slot pays out and the typical size of those wins. Low-volatility slots pay more frequently but in smaller amounts — great for relaxed play and stretching your balance. High-volatility slots pay out less often, but when they do, the multipliers can be significant. They're the go-to choice for players who crave excitement and are chasing bigger wins.
At b777, slots are organized into three categories. The platform makes it easy to choose by displaying the volatility level on each game card — before you even spin for the first time.
Almost every modern slot has a free spins feature, triggered when you land enough scatter symbols on the reels. During free spins, you don't pay for the rounds and all winnings are credited as normal. Some games also apply multipliers during this phase — that's when the biggest payouts at b777 tend to happen.
Beyond in-game spins, b777 offers free spins as a welcome bonus, through seasonal promotions, and on the daily Wheel of Fortune. These are spins on selected slots with no additional deposit required.
Megaways is a game engine created by BTG studio that changed slots forever. Instead of fixed paylines, the reels change height on every spin, creating anywhere from 324 to up to 117,649 ways to win in a single round. At b777, you'll find dozens of Megaways titles — a completely different experience from traditional slots.
Slots are entertainment games. The fun is in the experience — the animations, the bonus features, the excitement of a big spin. b777 encourages you to set a session limit before you start, use demo mode to explore games risk-free, and never bet more than you can afford to lose. Our Responsible Gaming has practical tools for that.

Real experiences from Brazilian players
"I started Gates of Olympus with R$ 50.00 and ended the session with R$ 640.00. The slot loads super fast on my Android and the animations are incredible. I've never seen a platform with this many titles in Brazil."
"I love trying demo mode before betting for real. I tested about ten new games before settling on Big Bass Bonanza. I hit the free spins bonus in my very first real-money session — walked away with R$ 380.00 from an R$ 80.00 deposit."
"b777 has the Megaways I've been looking for forever. I play Bonanza almost every day on my lunch break on my phone. The turbo spin is perfect — spins super fast without sitting through the animation. I cashed out BRL 220.00 last week, hit my account in 7 minutes via Pix."
