Statistics
Frequently Asked Questions
How does BloomStroke work?
A faint silhouette target appears on the canvas. Drag your finger or cursor to draw strokes that are mirrored across rotational symmetry. Fill the silhouette as completely as possible within your stroke budget, then tap Bloom to submit.
What do the difficulty levels change?
Easy uses 4-fold symmetry with a generous stroke budget. Medium uses 6-fold with a standard budget. Hard uses 8-fold with a tight budget. More folds make it easier to fill space but harder to control precision.
Is the daily bloom the same for everyone?
Yes. The daily silhouette, symmetry, and color palette are generated from the UTC date, so every player worldwide gets the same challenge each day.
How is the score calculated?
Your score equals the percentage of silhouette pixels covered by your strokes, minus a penalty for strokes that overflow outside the silhouette. Grades: S (95%+), A (80%+), B (60%+), C (below 60%).
What Is BloomStroke?
BloomStroke is a daily generative drawing game where your free-form strokes are mirrored across a chosen rotational axis to create bloom-like symmetrical patterns. You pick a symmetry mode — four-fold, six-fold, or eight-fold — then draw inside the day's silhouette target. Every brushstroke is reflected instantly, turning simple gestures into intricate mandalas. At the end of each session you receive a score based on how closely your bloom fills the target, and your artwork is added to the session gallery. Each day's silhouette changes with the calendar. The canvas runs entirely in your browser with no upload or account required.
How to Play BloomStroke
Drag on the canvas to draw. Your stroke is instantly mirrored 4, 6, or 8 times around the center. Fill the faint silhouette target within your stroke budget, then tap Bloom to see your grade.
Why Generative Drawing Games Spark Creativity
Rotational symmetry acts as a creative scaffold. By constraining how your strokes are reflected, the game removes blank-canvas anxiety and replaces it with a guided structure that produces satisfying results almost immediately. The daily silhouette target borrows from puzzle game design — there is a concrete goal, a score, and a clear endpoint — but the path to the goal is open rather than predefined. Artists find it useful for exploring composition under constraints. Non-artists find it a low-stakes way to experience the satisfaction of making something visually pleasing. Completing the daily bloom also contributes to a streak, reinforcing the habit of creative play.
