For sports lovers the world over, the last week of June means the Wimbledon grand slam tennis tournament. Tennis is one of the most popular spectator sports but there are not that many online slot games based on it as there are on sports like soccer, basketball or golf. However the two leading online casino software providers, Microgaming and Playtech, offer fantastic tennis themed online slots.

The Microgaming tennis themed online slot game is appropriately titled Centre Court. It was released on the occasion of Wimbledon and has the reels set in the background of lush green courts. The thematic symbols used include tennis ball, trophy, match point logo, tennis players in action and high value cards. The card symbols display tennis accessories like ball, cap and wrist band. The main symbols get animated during win combinations. The trophy is the wild symbol and it also offers the highest fixed jackpot of 1,000 coins when five of them are aligned on an active payline. The tennis ball is the scatter symbol. Two or more of these symbols appearing anywhere on the reels award scatter payouts. Three or more scatter symbols trigger the free spins feature with a thunderous applause from the spectators. The feature awards 18 free spins with a mystery multiplier. The multiplier can randomly take values of 2x, 3x, 4x or 5x. Another attraction of the Centre Court free spins round is that the wild symbols can appear stacked on any reel. This tennis themed online slot offers the optional Microgaming gamble game. After any win players have the choice of staking the payout in the gamble game. Players can opt to double the payout by trying to guess the color of the card or quadruple the payout by trying to guess the suit of the card. However, if players guess incorrectly then they will lose the payout itself. Centre Court is live at all Microgaming online casinos like Platinum Play, Gaming Club and Golden Riviera.

The Playtech tennis themed online slot game is titled Tennis Stars. It is a 40 paylines slot game with four rows of symbols across the reels. The male and female tennis players award the highest line payout of 5,000 coins and get animated in winning combinations. The other symbols include tennis shoes, tennis balls and high value card symbols.The trophy is the wild symbol that appears only on reels 2, 3 and 4. When it appears on all three reels simultaneously it awards a payout of 10 times the total bet and also triggers 15 free spins with tripled payouts. The free spins can be retriggered infinitely.The pair of tennis rackets awards scatter payouts and also triggers the Championship Bonus game on the second screen. The player selects one from the male player and female player. He then chooses a flat serve or a slice serve. The players may lose some points but always wins the game. Bonuses are awarded depending on the game score and the number of aces served. If four aces are served in the game an additional multiplier of 5 times is applied.
