Our Review of One Million Reels BC
One Million Reels BC Review
One Million Reels BC by Rival is a simple three reel game with five fixed lines, wild multipliers and a progressive jackpot sitting on top of everything.
Theme and first impressions
The game is set in a goofy prehistoric world. On the reels you see a caveman, a cavewoman, a T Rex and different colored dinosaur eggs. The graphics are basic by modern standards, but the theme is clear and easy to follow. Sounds are old school slot style, so this feels more like a classic machine than a modern video slot.
Reels, lines and betting
The layout is very straightforward. There are three reels and five fixed paylines. You do not choose how many lines to play. Every spin uses all five lines.
Bets are set up around coins. You can adjust your coin value, then choose how many coins to bet per line. In practice, the total stake per spin runs from 0.75 at the low end up to 3.75 at the top. That keeps the game fairly small stakes, with no huge bet options.
Because the lines are fixed, raising or lowering your stake only changes your coin size and how many coins you put on each line, not the number of ways to win.
Symbols and payouts
The paytable is classic three reel style. Wins are paid for three matching symbols along an active line. There are no wins for two of a kind.
- T Rex is the key symbol. It is the wild and the way to the progressive jackpot.
- Caveman and cavewoman pay in the middle range.
- Dinosaur eggs in different colors cover the lower and mid wins.
The top fixed jackpot is shown in coins on the paytable, and on top of that there is the progressive prize that can climb very high over time.
Wild symbol and multiplier
The T Rex symbol is the wild. It can stand in for any regular symbol to complete a winning line. There is no scatter symbol in this game, so the wild can substitute for everything that pays.
On top of that, T Rex also acts as a multiplier. Any win that includes one T Rex has its payout doubled. If two T Rex symbols are part of the same winning line, the payout on that line is multiplied by four. This can make even the lower paying egg symbols worth a bit more when the dinosaur helps out.
Progressive jackpot
The main reason to play this slot is the progressive jackpot. A small part of every eligible bet from all linked casinos goes into this shared prize pool. It keeps rising until someone hits the right combination.
To win the progressive, you need three T Rex symbols on a specific payline. It has to land on the top line with the maximum number of coins bet. If you hit three T Rex on another line or with fewer coins, you still get a strong fixed payout, but not the progressive pot.
The game usually shows the current jackpot amount above the reels, so you can see exactly what you are chasing. There is no separate bonus round for the jackpot. It is won directly from a normal spin when the right symbols line up.
Game flow and features
The gameplay is very basic. You set your coin size, choose how many coins per line, then hit spin. There is an auto play option if you want the game to spin on its own for a set number of rounds. That is handy if you are grinding for the jackpot and do not want to click every time.
There are no free spins, no pick bonus and no gamble feature. Every spin is just about lining up symbols and hoping for T Rex to land in the right spots.
RTP and volatility
The theoretical return to player is around 90.6 percent, which is low compared to many modern online slots. Part of the return is tied up in the progressive jackpot, so normal hits can feel a bit lighter.
Volatility is on the lower side. Wins tend to come fairly often, but many of them are small, especially when you are not hitting the wild multipliers. The real spikes in payout come from lines that include one or two T Rex symbols, and of course from the rare progressive hit.
Mobile and accessibility
This is an older Rival title that was originally built in older tech, so support can vary by casino. Some sites offer it in a wrapper that works fine in a browser on desktop and may work on some mobile devices, while others may only support it on desktop. There is no extra touch interface or special layout for phones. It is essentially the same classic three reel screen wherever you play.
Who will like this game
This slot is aimed at players who enjoy simple three reel machines and like chasing a large progressive prize. If you want lots of features, free spins or complex mechanics, this one will probably feel too bare. If you are happy with straightforward spins, wild multipliers and a single big jackpot goal, it does the job.
✓ Pros

Bottom Line
Final verdict on One Million Reels BC
One Million Reels BC is a throwback to classic slot machines. Three reels, five fixed lines and a single big goal in the form of a growing jackpot keep things very straightforward.
Who is this slot best for
- Fans of classic slots who like simple three reel gameplay with no complex rules.
- Jackpot hunters who are willing to trade features and higher RTP for a shot at a big progressive prize.
- Casual players who prefer low volatility and steady small hits, especially when wild multipliers land.
If you enjoy modern feature heavy games, the lack of free spins and bonus rounds here will likely put you off. But if you want an easy to follow Rival title where every spin could, in theory, drop a life changing jackpot on that top line, this prehistoric themed machine is still worth a look.
