Better than all the other ship games
I love how kid-friendly this version is. Easy to play on non-duos, too and the game tells you when to pass to the other player! Well done!

What's New in Knotty Navy
1.0.2
October 26, 2026
Shut your Duo and the lid now lies sideways: hold it with the hinge along the top, and it opens straight into play. Your shots cross the fold. Each peg hops off one of your ships still afloat, over the hinge and into its hole, one ship per shot in a salvo. Fire coming back falls in from over the top, one peg at a time. A sunk ship rocks as it settles into the rack, the board that's hit is the one that shakes, and play against the computer moves along quicker. The main menu now marks each rank you've beaten.
