Complete the scene or advance to the next level by matching three or more similar objects. Goals vary for individual match-3 games. Some games require the player to make the entire game board a uniform color through matches. Other games require players to match a required number in each scene to collect specific items that can be used to achieve power-ups later or unlock hidden items by matching. Games involving bubble or marble shooting are also considered match-3 games because the player must match different colored balls, balloons or marbles to pop or destroy chains and unlock achievements. Bejeweled, Jewel Quest, Fishdom, Bubble Town and Luxor are popular match-3 games.
