SumDay: Calendar Puzzle

SumDay is a unique puzzle calendar app that transforms everyday dates into an engaging and intuitive puzzle experience.

Instead of simply viewing a calendar, users interact with it by tracing dates in specific patterns to complete stages. Each stage is carefully designed around real calendar structures, creating a blend of logic, memory, and spatial reasoning challenges.

The app offers a refreshing way to experience time. Each level is based on actual years and months, allowing players to naturally connect gameplay with real-world calendars. As difficulty progresses, players encounter increasingly complex patterns that require planning, observation, and strategic thinking.

Gameplay

Each stage presents a calendar grid with specific rules or target patterns. The player must determine the correct path through the dates by tracing them in the right order.

The goal is not speed, but clarity of thought and precision. Every solved stage provides a satisfying sense of completion as the calendar transforms from ordinary structure into a solved puzzle.

Concept

SumDay was designed around the idea that time itself can become a puzzle. A calendar is usually something we passively read, but here it becomes an interactive space where each day has meaning within a structured challenge.

By combining familiar calendar layouts with puzzle mechanics, SumDay creates a new way to experience time, making everyday dates more engaging and memorable.
