The era called the Stone Age was approximately two and a half million years ago and lasted over three million years. This was before the machinery, currency, let alone slot machines. Nevertheless, this is the theme of Endorphina’s slot, helpfully named Stone Age.
Primitive people, primitive tools, furs and, most importantly, stones, are all things you would expect to see in a slot about early humans. The Stone Age definitely has all of those things. The slot is set against a cave wall, which has painted stick figures and the title at the top. The menus look like they are made of hides, clay, or wood depending on where it is, and the whole theme combines to portray an ancient and primitive feeling.
Theme & Special Functions
The symbols in the game include cave paintings: one of warriors, one of an animal that looks a little like a faceless horse, a mammoth, a necklace made of teeth, a stone knife, and a Stone Age man and woman. The game has a bonus symbol of a stone circle or wheel with a pointer. This symbol functions as the wild and the scatter for the game. It can replace any other symbol except the expanding symbols during the free spins round, to be discussed later.
If a single bonus wheel symbol appears anywhere, then you win a bonus prize, the size of which is calculated by the size of the original bet. Three or more of these bonus symbols, however, triggers the Hit Stone Age bonus round. This is a free spin round with ten free spins but with one notable difference.
Before you start the free spins round, the stone wheel scatter comes forwards and you spin it in order to choose any one of the standard symbols. If this chosen symbol appears during the ten free spins, then it expands to cover the entire reel, greatly increasing the win potential. Note that if there is no win potential when the chosen symbol appears, then the chosen symbol will not expand, though this is a rare occurrence.
Finally, there is also the Stone Age Jackpot up for grabs. This ultimate prize is worth five thousand times your original bet and can be won by lining up five mammoth symbols next to each other on any row. This mammoth prize, pun entirely intended, can theoretically net you five hundred thousand coins if you bet the maximum number of coins. This can end up well over a million eurosif you use higher coin values.
Like a large number of other slots, Stone Age also has a gamble feature. If you get a win, you can then bet your win on a double-or-nothing extra game. You pick a card, and if your card number is higher than the dealer’s card, your winnings are doubled, but if it’s lower, you lose. If you and the dealer have the same number, it’s a tie game.
Stone Age is a standard five-reel slot with twenty paylines. Coins range in value from a cent to five euros, and you can place between one and a hundred coins on a single payline. This means that you can bet up to five hundred euroson a line. This means your maximum bet is an insanely high ten thousand euroson a single spin.
The game has a solid betting range, accommodating both the average punter and the super-rich. Like almost all other games from Endorphina, Stone Age has an RTP of 96%, which is not the highest in the market, but still gives out decent returns by slot standards. Combine this with good graphics and solid mechanics and it’s clear how good the game is.
