Connect Master is a tile-matching game that completes matches via connection lines. The game presents the player with classic-themed tiles that feature images from daily life, including a wide selection of frozen desserts, breakfast foods, whole fruits and vegetables, cafe drinks, clothing pieces and vehicles.
To win a level, the player must remove all tiles from the playfield in pairs with no more than three lines of connection between each match. They're given a limited amount of time to complete this task. To remove the tiles faster, they can use a hint to show the next connection. They can also use boosters to speed up gameplay. For example, they can use a Shuffle booster to rearrange the tiles into different positions or a Refresh booster to change the images displayed on the tiles to a different set that they consider easier. The game automatically displays a Hammer tool as well that randomly clears two tiles after the player performs a separate match using a tile that has a hammer icon on it.
Connect Master has a star-achievement system. After a player earns a certain number of golden stars across several levels, they receive access to a treasure chest filled with loot, including extra hints and boosters. They also receive extra coins that they can use to buy more hints and boosters.
