SeaBattle puzzles are a single player version of the classic game many of us used to enjoy as children. Using pure logic and requiring no math to solve, these addictive puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages.

A typical SeaBattle puzzle consists of a 10x10 grid containing a hidden fleet of ten known ships. The only information is numbers telling how many ship segments are in each row and column, and some given ship segments in various places in the grid. The object is to discover where all ten ships are located in the grid.

The game includes a pencilmarks feature to place temporary water or ship segments when solving very hard puzzles, and a highlight excluded squares feature to help see where certain ship sizes can be placed.

For more fun, Conceptis SeaBattle includes a Weekly Bonus section providing an extra free puzzle each week.

ALMOST a perfect puzzle game

Emily, Sean, & Baby Oliver

...if only they would make some grids that were larger than 10 x 10 and housed more of the large-sized ships, maybe even a new 5 or 6 length ship. With 10 x 10 and so many small ships vs larger ships, you are left to guess locations and use the checker to see if you're right, which feels like cheating to me. Also, each game only takes me ~2 min to solve, and I wish they were larger and took a little more time so I got more for my money.

Fun game!


I’m getting better and better at this one, but am still needing a little help with strategy. Luckily the game gives you that help, but I wish I didn’t need it.

Perfect now!

U don't need to know my name

I really enjoy this puzzle! Also, thank you Conceptis for listening to us and adding the option not to show mistakes.
