Tc65 Bonanza Big Time Slots — Game Environment
Bonanza is a highly influential video slot by Big Time Gaming (BTG) — the game that brought the Megaways mechanic into the mainstream. Released in 2016, it has since been recognised as a landmark title in the slots industry.
The core attraction of this game is the changing reel height on every spin — generating anywhere from just a few thousand up to a maximum of 117,649 Megaways per spin. Add to that Cascading Reels and an ever-increasing Multiplier during Free Spins, and the result is a truly remarkable experience.
In the tc65 Bonanza Big Time Slot section, you'll find detailed information on every mechanic, symbol payout structure, Free Spins feature, and RTP for this game.
Bonanza's backdrop is a gold mine — gemstones, gold nuggets, and mining tools make up the game's visual identity. A separate horizontal reel strip sits above the main grid, delivering fresh symbols with every spin.
Megaways is Big Time Gaming's patented reel mechanic — one that completely overturns the limitations of traditional slots.
In a standard 5×3 video slot, every reel always has 3 rows — giving 243 fixed ways to win. In a Megaways slot, the height of each reel changes independently with every spin.
Bonanza has 6 main reels — each can display anywhere from 2 to 7 symbols at once. Multiply the symbol count across all reels to get the total Megaways. When every reel shows the maximum 7 symbols: 7×7×7×7×7×7 = 117,649.
| Reel 1 | Reel 2 | Reel 3 | Reel 4 | Reel 5 | Reel 6 | Total Megaways |
|---|---|---|---|---|---|---|
| 2 | 2 | 2 | 2 | 2 | 2 | 64 |
| 4 | 4 | 4 | 4 | 4 | 4 | 4,096 |
| 5 | 6 | 7 | 6 | 5 | 4 | 25,200 |
| 7 | 7 | 7 | 7 | 7 | 6 | 70,057 |
| 7 | 7 | 7 | 7 | 7 | 7 | 1,17,649 |
Megaways slots use an "Anywhere Pays" system instead of fixed paylines — matching symbols on adjacent reels from left to right count as a win, even if they aren't on the same row. Typically, 3 or more matching symbols running left to right will trigger a win.
Big Time Gaming (BTG) holds the patent for the Megaways mechanic. Other game studios license this mechanic from BTG to use in their own titles — a significant business model in the modern slots industry.
| Studio | Popular Megaways Games |
|---|---|
| Big Time Gaming | Bonanza, Extra Chilli |
| Pragmatic Play | Gates of Olympus Megaways |
| Red Tiger | Various Megaways titles |
| Blueprint Gaming | Diamond Mine Megaways |
This list is for informational purposes — availability of specific games may vary by platform.
In All-Ways slots (5×3), there are always 243 ways to win. In Megaways, the number of ways changes with every spin — sometimes fewer, sometimes an enormous number. This dynamic quality is what makes Megaways unique.
Tc65 Bonanza Big Time Slot — Game symbols & reels
One of Bonanza's headline features is Cascading Reels (also called "Avalanche" or "Tumbling Reels" in some slots). Winning symbols are removed from the screen and new symbols fall in from above — potentially creating another winning combination.
This sequence can occur multiple times in a single spin — the Cascade keeps going as long as new winning combinations keep forming. This can multiply the value of a single spin many times over.

The symbols in Bonanza are themed around mining — each one has its own value and role in the game
The most valuable symbol in the game — landing 6 of them gives the highest payout.
x50 (6 of a kind)Second-highest tier — red gemstone, contributes to big wins.
x40 (6 of a kind)Third-tier symbol — green gemstone.
x30 (6 of a kind)Fourth-tier symbol — blue gemstone.
x25 (6 of a kind)Substitutes for any symbol except Scatter — plays a key role during Cascades.
WildLand 4 Scatter symbols (G-O-L-D) anywhere on the reels to trigger Free Spins.
ScatterBonanza features six low-value card-based symbols that appear most often on the reels but pay out less. In the Megaways system, multiple combinations of these symbols can form within a single spin.
| Symbol | 3 | 4 | 5 | 6 |
|---|---|---|---|---|
| A | X1 | X2 | X5 | X15 |
| K | X1 | X2 | X5 | X15 |
| Q | X0.5 | X1 | X3 | X10 |
| J | X0.5 | X1 | X3 | X10 |
| 10 | X0.5 | X1 | X2 | X8 |
| 9 | X0.5 | X1 | X2 | X8 |
The multipliers above are expressed as multiples of total bet — refer to Bonanza's actual Paytable for details.
One of Bonanza's standout features is a horizontal reel strip running across the top of the reels, adding symbols above reels 2 through 5. It acts as an extra row outside the main grid and contributes to the overall Megaways count.
The Free Spins feature is arguably the most exciting part of Bonanza. Landing all four GOLD Scatter symbols anywhere on the reels triggers the Free Spins round.
Landing all 4 G, O, L, D Scatter symbols anywhere on the main game reels triggers Free Spins — typically starting with 12 Free Spins.
During Free Spins, every successful Cascade increases the Multiplier by 1 — starting from x1 and theoretically going up without limit. The more Cascades you land in a single Free Spin, the higher the Multiplier climbs.
If GOLD Scatters land again during Free Spins, you receive additional Free Spins — typically 5 extra spins per Scatter.
Even when a spin ends during Free Spins, the Multiplier carries over from where it left off — it only resets once the entire Free Spins round is complete.
This image is conceptual — the Multiplier is theoretically unlimited.

Say a spin activates an x20 Multiplier — if you win ৳1,000 on that spin, your actual payout becomes ৳20,000. A high Multiplier combined with a high Megaways count creates Bonanza's biggest win potential.

If you're sitting down to play Bonanza or any Megaways slot for the first time, follow the steps below.
Once the game loads, click the "i" or "?" button to view the Paytable. In Bonanza, use it to learn symbol values, how Scatters work, Free Spins trigger conditions, and Multiplier rules. Note that details may vary slightly between versions.
Bonanza is a high volatility game — meaning frequent small wins are unlikely; instead, there is a chance of larger wins less often. Start with smaller bets to get a feel for the game, and choose a stake that fits your session budget.
Press the Spin button — the Megaways count is set at the start of each spin. When winning symbols are removed, the Cascade begins. Each Cascade creates a new chance to win on the same bet.
Landing all four Scatter symbols — G, O, L, D — anywhere on the reels triggers Free Spins. This is the primary opportunity for the highest payouts. During Free Spins, the Multiplier increases with every Cascade.
Autoplay can burn through your balance quickly. Set limits and keep a close eye on your budget.
Keep track of how much you've wagered and how much you've won back each session. Understanding your own patterns over time can be genuinely helpful.

At tc65, we always promote mindful and responsible gaming. High Volatility slots can drain your budget quickly — so set your session budget and limits before you start playing.
