Battleship Royale
Hasbro
Many will sink!
Face off with up to 6 players and compete to be the last afloat in the Battleship Royale game! In this exciting party game take on the beloved Battleship search-and-find game, all players share one Battle Grid to mark hits and misses. Instead of placing physical ships, they're dealt Ship cards that reveal their fleet and where their ships live on the grid. The cards slip into handheld Command, so players can secretly track hits. Roll the die to fire to fire on opponents. The last one with a ship left on the grid wins! Ready to level up? Play in Advanced Mode and create an elite fleet with the addition of submarines, which can share coordinates with ships and have ship-detecting Sonar capabilities! The Battleship Royale gameboard stores easily and has built-in trays for pegs. It's a thrilling game for Family Game Night and makes a fun gift for kids ages 8 and up!
Inventor: David Yakos. Assistant Designer: Branson Faustini (Interesting factoid; came up with the name Battleship Royale).

Dunk Hat
Hasbro
Hasbro’s Dunk Hat is a fast-paced, laugh-out-loud game created by David Yakos.
In the Dunk Hat game players get 3 throws and 2 targets, but all it takes is 1 shot to tip the tank and win! Players brace themselves, and the suspense grows as 1 player places the hat filled with water on his or her head. The other player throws a foam ball at one of the targets. If they hit it, the water releases and soaks the person wearing the hat. Now, it's time for someone else to wear the Dunk Hat game hat. Who will get soaked -- and who will stay dry?!
