Birthday Bash is a 15 payline, 5 reel video slot that includes a built in bonus round and hold feature among a festive birthday theme. Among the game's many symbols are a birthday cake, balloons, candy, party hats, greeting cards, and flowers. A firework symbol gives players a payout of up to 500x their wager amount. A birthday present symbol works as a scatter symbol on the third reel and triggers a mini game wherein players pick buttons to reveal big prizes.
Commenting on the game's release, WinADay Manager Michael Hilary said: “Last year about this time we were running a contest on Facebook to name our new America-themed game, Grand Liberty, which made its debut in July. Since then we’ve added four more new slot games – Chinatown, Enchanted Gems, Hold the Riches, and Joker’s Tricks plus a keno game called Keno101 – and we have a new pet-themed game in the works that should be ready to play in early August.”
