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).

Pinball Machine Maker: Gumball Rally
Thames & Kosmos
The sweetest pinball machine ever!
Build a pinball machine that uses edible gumballs as the pinballs. First, follow the step-by-step instructions to assemble the machine. Then lay out the targets and obstacles on the playfield. Finally, test and refine your design while you practice your pinball skills! Hit the targets with the gumballs to score points. The gumballs whiz around the machine, bouncing off bumpers, spinning spinners, ringing the bell, and sliding down tracks. Can you shoot the gumball up the ramp and into the goal to ultimately claim your sweet reward?

Gumball Machine Maker
Thames & Kosmos
Super Sweet Stunts!
Build your own gumball machine and learn physics lessons at the same time. A turn of a handle dispenses one gumball at a time out of the storage globe and down the track. As the gumballs roll down the track, they perform cool tricks. Add pieces like a pendulum, pulley cups, funnel, trampoline, pinball launcher, and domino track to your machine to see these wacky stunts in action. Each segment of the track teaches a different lesson in physics, allowing users to explore force, motion, momentum, gravity, energy, simple machines, and more. The gumballs land in a collection cup and are easily returned to the globe for another run. The track segments can be repositioned to create an almost limitless number of different gumball machines. Trial-and-error experiments teach in a fun, hands-on way. Will your gumball successfully make it to the end of the track, or will you have to reengineer your gumball machine to make it work?
