Marble Track - a social casino slot game built around five reels and three rows of fruit symbols: cherries, lemons, grapes, watermelons and golden bells. Each press of SPIN sets the reels in motion, and they come to a stop one after another from left to right. The top, middle and bottom rows act as paylines, and a line pays when three or more matching symbols run from the leftmost reel, with four in a row paying double and five paying four times the listed value; the payout for every symbol is shown in the paytable on the info screen, where the full rules are also described. The bet starts at 20 coins and changes in steps of 20 with the minus and plus buttons up to 200, while MAX BET sets the highest amount the current balance allows, and all bet controls are locked while the reels turn. Three or more bells anywhere on the reels open a bonus round of five free spins with doubled wins, and a summary panel shows the total collected once the round ends. Every spin result is random and decided by luck and chance alone, since the app is a simulated game of chance and a social casino, and nothing pressed or changed after a spin begins has any effect on the symbols the reels settle on. Winning lines light up on the reels, and large wins open a separate panel with the amount. Coins are purely virtual, the app involves no real money at any point, and coins come from three sources: a starting balance is granted on the first launch, a free daily grant becomes available every 24 hours and unlocks early whenever the balance drops below the minimum bet, and further coins come from wins on the reels. The progress screen holds the daily grant with a countdown to the next one and a statistics block with total spins, winning spins, top win, total won, total bet, bonus rounds played and the longest winning streak. The balance, the chosen bet, unfinished free spins, statistics and settings are kept between launches. The settings screen switches win effects on or off, sets the reel speed to normal or fast and resets all progress back to the starting balance. Access to the game is meant solely for people who have reached the legal gambling age where they live.
Matching symbols across five reels pay virtual coins and open free spin rounds.
