For hundreds of years, in the wake of its invention in the 1600s, roulette had been a preserve of land-based casino operators. The countless present-day roulette variants, especially the innovativeness behind the flash game called Double Bonus Spin Roulette, are beyond the alleged inventor Blaise Pascal’s wildest dreams.

Double Bonus Spin, which is the brainchild of the then independent gaming company named International Game Technology—it has since been taken over by the London-based gaming giant Gtech—is an enhanced video slots that has graced online casinos since May 2012.

The bonus spin, whose 50% chance of being triggered results from its symbol’s relatively larger size (1.5 bigger) compared to the adjacent numbers, partly inspired the name Double Bonus Spin Roulette. A new pocket in Double Bonus Spin Roulette adds thrill to the players’ quest for predicting the rotating ball’s stopping point.

Double Bonus Spin Roulette: Game Review
Generally, the Double Bonus Spin Roulette layout is somewhat synonymous with the American Roulette, including its similar roulette wheel numbers 1 to 36.

The presence of the green-coloured “0” and “00” pockets is not the centre of interest in Double Bonus Spin Roulette; instead, a B-encased yellow-coloured pocket that stimulates a second three-ringed roulette wheel (bonus bet) and doubles up players’ winning chances steals the show.

The main wheel has two rings: only the larger outer ring (and the two outer rings in the second wheel) is numbered, lettered, and coloured; the smaller inner ring, whose markings match up with those on the other ring, is where the rotating ball stops.

Pressing betting chips then immediately pressing desired spots on the betting grid and/or race track places the bets in Double Bonus Spin Roulette, whose strategically valued chips are $1, $5, $25, $100, $500, and $1K. Afterwards, you press the “Spin” or “Auto Spin” icons.

Double Bonus Spin Roulette has a minimum bet of $1.00, but it is a mere $0.10 bet in some models. The maximum bet is $1000.00, although there are models that prefer a table max of up to $3000.00.

Maximum bets vary, ranging from $50.00 for Straight Up and $300.00 for Six Numbers in Inside bets to $600.00 for Dozens and $1000.00 for Red-Black in Outside bets.

Payouts for Inside and Outside bets imitate suchlike variants. The payouts unique to Double Bonus Spin Roulette are two. Yellow bonus bets pay X12, X6 and X4 for Straight Bonus, Split Bonus and Trio Bonus, respectively. Bonus Spin bets: Straight Bonus, Split Bonus and Trio Bonus bets increase to 120:1, 60:1 and 40:1 in one wheel, whereas it is tenfold for two wheels.

The free spin and 1200X payout make up for the lack of a progressive jackpot and pay lines. The interface is orderly; an interesting aspect about the HD graphics is the dragon icons in the betting grid that, when pressed, bend their heads up and roar excitedly.

Double Bonus Spin Roulette: Game Strategy
The RTP rate in the Double Bonus Spin Roulette game is 98.06%, whereas the house edge is 1.94%. A worthwhile strategy is constantly staking on the yellow pocket, which is the gateway to the bonus round, because it has a high ‘return on investment’.
