2020 Jelly Time is block puzzle game that features candy instead of classic wood blocks. The player earns points, coins and up to three stars per level across 60 levels by creating rows and columns on a 10x10 grid board in a candy world primarily made of jelly candy and molded gelatin forms.
The player must complete missions, such as achieving a specific score marked with a trophy icon. They reach a certain score by placing roundish square jelly candies grouped into polyomino shapes on the grid. The shapes have specific amounts associated with them based on the number of grouped candies per shape.
When the player creates rows and columns with the shapes, they earn gold coins. Additionally, they can watch ads to earn extra coins. When they perform well, rainbow-sprinkled chocolate-coated bonbons appear as bonus bombs that explode nearby jellies to also give the player more coins. The player can even win a bonus based on their score and stars. If they ever run out of moves, they must restart the mission.
2020 Jelly Time also provides boosters to help the player complete the levels. When they have enough coins, they can use the button marked with a lightning bolt near the upper-right corner to purchase an option to change the types of shapes below the board, clear a single cell on the grid, clear a specific type, or clear an entire area. During a game, a bonbon might appear at any time to reward the player with rocket-style abilities that take out a row, column or both with a single move. Any unusable empty spaces on the board act like bonus jellies to complete a row or column.
