Guide
Same puzzle. First finished board wins. Pencil marks are for candidates. Wrong digits stay visible so you can fix them.
Completing a row, column, or box earns that strike. Three misses can grant the opponent a reveal. Advertisement starts loaded in an online battle — watch a short sponsored break to send it. The other player is paused while it plays. After it lands, a 3×3 of their filled (non-given) cells can clear. That is the bomb.
Tap a cell, tap a number. Pencil toggles candidates. Erase clears your entry. On a phone, use View opponent to swap boards instead of squeezing two grids.
Don’t click ads. Don’t refresh mid-match if you can avoid it. If a room drops, create a new code.
