Bubble Letters is a connect, crossword-style, word-search puzzle game with a floral theme. Across thousands of levels, the player attempts to fill empty crossword spaces with words created from round-cornered letter tiles.�
Against a stunning floral backdrop, the player receives the letters for a level inside a circle on the right half of the screen. They must attempt to guess the correct words based on a few pre-filled letters and the number of empty spaces on the left half. To make a guess, they draw connecting lines between the letters from the first letter of the word to the last. If they guess correctly, the word appears in one set of empty spaces. If they guess a secret word, the game credits them. It also offers helpful tools that make guessing easier, such as hammer, hint and shuffle tools.
Bubble Letters rewards the player in numerous ways. The player receives points and diamonds. If they create words in a streak, they receive a points multiplier bubble at the lower-right corner. They can also double their diamond winnings by watching an ad.�
After the player succeeds across a certain number of levels, they unlock a mystery gift that contains diamonds and helpful tools or receive a new floral backdrop. The player also receives a gift if they guess six secret words across multiple levels. The game features achievement medals in four areas (Master of Words, Event Superstar, Gem Collector and Starfall Seeker). The player receives rewards for collecting a specific number of items, such as lilies, stars and bees. There's even a daily rewards wheel.
