A game publisher, King, released a lot of casual match-three puzzles under the Candy Crush franchise. One of them is Candy Crush Jelly Saga. It has new mechanics (e.g. of spreading Jelly over the field to defeat Jelly Queen), boosters, and bosses. The game also has a real-time mode for contests: players connect with their friends and solve puzzles in a PvP mode on a timer. There is, of course, a leaderboard to motivate players to set new scores.
Candy Crush Saga is a first match-three series that has managed to get over $1 billion in revenue. Jelly, as a game from the series, is also incredibly successful: it has amazing ratings in app stores — players think it’s bright and fun. Apart from that, the title has over 3000 levels — and we created some of them.
