Doubles, which was released on October 1, 2015, is an online game made by Yggdrasil Gaming. A retro-themed and vividly packaged slot game, Doubles has an unusual game play, although some of its features—such as the absence of pay lines and the usage of 243 ways—are similar to other Yggdrasil’s games such as Penguin City (July 2018) and Big Blox (August 2016).

The noun “doubles” refers to things that appear in twos. Accordingly, the Doubles’ symbols can show up on the grid in twos, just like the orange-and-blue brand logo that is made of two interlocking letter D’s; however, the symbols mostly appear in singles. Doubles players win after matching between three and ten symbols, either standalone or in twos.

Doubles Game Characteristics
Doubles has a dynamic volatility rating, which ranges between 18 and 100. The 5X3 grid lets the players win in 243 different ways, whereby the matching symbols should be in reels that are strictly side by side. For instance, a winning combination can result from a particular symbol appearing thrice (in reels one, two, and three—from left to right) but not with an empty reel between them (like a particular symbol in reels one, three, and four).

The nine classic Doubles’ symbols are: a blue diamond, an orange-colored “7”, a golden horse shoe, a green star, a pair of cherries, a slice of a watermelon, an octagonal orange fruit, a hexagonal yellow lemon, and a hexagonal purple lemon.

Doubles’ starting page advertises it two major features: the double symbols to be won in 243 ways and the players’ freedom of personalizing the game play (after getting the regular and generous ten free spins), where they pinpoint a preferred symbol that will be doubled up.

Doubles offers a choice of fourteen coin values: $0.01, $0.02, $0.03, $0.04, $0.05, $0.07, $0.10, $0.16, $0.20, $0.30, $0.50, $0.70, $1.00, and $2.00. A result of multiplying coin values by 25 coins, the total bet sizes are: $0.25 (the minimum bet), $0.50, $0.75, $1.00, $1.25, $1.75, $2.50, $4.00, $5.00, $7.50, $12.50, $17.50, $25.00, and $50.00 (the maximum bet).
