How to play
- A grid shows several ships. One is red.
- Pick the square of the red ship: the letter for its column and the number for its row, counted from the top.
- The grid starts small and grows to ten by ten.
- The clock starts on your first tap and your time is saved. Every day has the same quiz for everyone.
Controls: mouse or touch. Made by CalcoTools.
Tips and strategy
- Say the column first, then the row, like C4.
- Rows are counted from the top, with 1 at the top.
- Run your finger along the top edge to the letter, then down to the red ship.
- If the answers look alike, check you did not swap the letter and number.

- From the top. Row 1 is the top row.
- Is this the same as Battleship?
- Similar names for squares, but here you only read where a ship is.
