In S.U.M. you'll put your Quick-Math skills to test! Fight very Uncool Monsters using Addition, Subtraction, Multiplication & Division. Level up and progress in the Campaign(s), or show your prowess in Endless Mode with Leaderboards.
In this math-based puzzle game, players enter dungeons, mines, forests, and other environments, facing off against "Uncool Monsters" on each floor. To defeat these monsters, players must solve the arithmetic problems they present, which can involve a combination of addition, subtraction, multiplication, and division.
As players progress, the math problems become increasingly complex, with expressions involving multiple operations. This challenges players to maintain both speed and accuracy in their calculations, providing an engaging and rewarding experience.
In addition to solving the math problems, players must strategically place their answers on the grid to trigger special abilities unique to their character classes. Aligning numbers in rows or columns can unleash bonus attacks, adding an extra layer of tactical depth to each encounter.
Clearing dungeons and defeating monsters earns players currency and experience points, which they can use to unlock new areas, characters, and upgrades. The game's campaign offers a linear progression, while the "Endless Mode" allows players to test their skills against increasingly difficult challenges, providing high replayability.
Players can choose between timed and untimed modes, allowing them to adjust the difficulty to their preference. The timed mode adds a sense of urgency, while the untimed mode is more forgiving, catering to both casual and more hardcore players.
One of the game's strengths is its ability to provide immediate feedback and satisfaction. Correctly solving a math problem results in visual and audio cues, reinforcing the feeling of accomplishment. This, combined with the game's retro-inspired art style and chiptune soundtrack, creates an engaging and satisfying experience.
