Words in Bubbles is a word game that features a bubble-popping element and theme-based play. In each level, the player's goal is to form words using partial letters in bubbles that drop from the top of the screen into a clear, round-bottom container. They must guess every word correctly to pop and remove all the bubbles from the container, win coins, and unlock the next level.
The game presents the player with a thematic clue and empty word spaces in the top center of the screen. The player uses the letters in the bubbles to fill the spaces. For example, they might use partial letters to create words that describe items found in a room, objects associated with a color or season, or the names of animals, plants and even planets. They can only form words when they select the partial letter bubbles in the correct order. That said, they can deselect an incorrect bubble at any time.
Words in Bubbles offers several tools to make selection easier. The player can use a green hint magnifier button to highlight only the bubbles that form a word, the orange lightning bolt button to reveal some letters in the word spaces, or a blue double arrow button to shuffle the bubbles in the container. They use their coins to buy more access to these tools over time. If they want to multiply the coins, they must simply view ad videos.
