Flick the Ship

Flick the Ship is a turn-based pencil-and-paper naval warfare game where 2-4 players use their skill in flicking a pencil across paper to fight each other, sea monsters, and sometimes even the seascape itself. Players collect experience points to level up their vessel, and can forge alliances with other ships to make massive fleets. By collecting gold doubloons, additional "mini-ships" can be bought for more casual, low-stakes play. —description from the designer
