At Toy Fair, ThinkFun’s booth was full of puzzles and a few games. We saw the next entry in their Escape the Room line: Secret of Dr. Gravely’s Retreat (available now, $22). Containing four packed envelopes of props, puzzles, and clues, the new case has a higher age range. “Mystery at the Stargazer’s Manor was big hit for us,” explained Kacey Templin, “but we had a lot of feedback to make the next one a bit more difficult, a bit more adult.” Thus, the recommended age moved slightly forward from 10 to 13 and up.

Color Cube Sudoku (March, $20) replicates a 6×6 Sudoku puzzle with nine colored cubes. Orient, spin, and swap cubes to solve a Sudoku puzzle using colors instead of numbers.

But I thought the coolest thing there was Spin-A-Roo (in stores in March, $20), a number counting game for the preschooler to second grade set. On your player mat, you have four numbers. You race to grab numbered discs off of the central spin-a-roo piece, either one up or down from the numbers you currently are showing. One neat thing about the game is the spinning element on the central unit: just spin it once and the board is repopulated with tiles — it’s actually fun to set up the next round!

RollerCoaster Challenge (summer, $22) is designed by the person that created Gravity Maze. In this, you’re taking several roller coaster elements, and buildling out tracks. You can try one of the forty challenge cards that come with the game, or — as I suspect I’d do — just use it to build your own coaster set. Currently on Kickstarter — ThinkFun’s first foray using the crowdsourcing platform — backers can receive an exclusive ThinkFun-colored blue car.
