Suika Game, also known as Watermelon Game, is puzzle games. The game was originally developed for the company's digital projectors; however, due to its initial success, the game was released on the Nintendo eShop in December 2021 only in Japan. In October 2023, the game was given a global release.
To earn points the player must combine two of the same fruits together, which creates a new fruit in the game's fruit cycle. The game allows players to view other player's ranks through an online leader board. Two years after the game's release, Suika Game exploded in popularity after being streamed by live streamers, particularly by VTubers.The game achieved over three million downloads by October 2023 and became one of the most downloaded games on the Nintendo eShop the previous month. The game also became prone to unofficial versions being created. Suika Game is a merge puzzle game focusing on stacking objects in a confined space, reminiscent to Tetris.The player, represented as a cloud called Poppy, is tasked with dropping a wide range of fruits in a box and aim for the highest score without having a single fruit cross the line at the top of the box and overflowing out, or else the game would end. In order to keep the fruits from overflowing out of the box, the player must match two types of fruits in order for them to merge into the next biggest fruit in the cycle, increasing the player's score. The bigger the fruits that merge the larger the point bonus is, with the largest merge the player can achieve is creating the titular suika/watermelon.If two watermelons merge, they disappear from the box. Suika Game has no time limit to rush the player with; but unlike with games like Tetris, the fruits are affected by physics causing them to hit off each other and roll away from where they were initially dropped.
