Gemfield Sweep

How to play

1. Start the daily or quick challenge. The center opening is always safe and opens automatically, revealing number clues. Everyone on the same link gets the same hidden field.
2. A number shows how many of the surrounding eight cells hide hazards. Tap a covered square to reveal it. Turn on Flag mode to mark hazards, or right-click on desktop.
3. Reveal all 54 safe cells before the three-minute clock runs out. A hazard costs one of three lives and 100 points. Each safe square earns 20 points; a full clear adds your remaining seconds to the score.

Daily boards change each UTC day. Quick boards use a fresh seed. Share a challenge to send the same initial board to a friend; their moves and score remain independent. No account, cash value, or real-money stakes.
