Ten furlongs are condensed to (7) inches, with very small horses, in the Desktop Derby, a 6-horse straight track that lets you win money while you teach the children the evils of pari-mutuel betting. The electric track pulsates and moves the nags along at a pace of about 45 seconds per race, with heart-stopping lead changes. The best part is that they're un-handicapable: a different horse, in a different lane, seems to win every time. Measures 9-7/8" x 3-1/2" x 2" high and runs off (2) "AA" batteries, included. (Stable the horses in the base between races.)

Imagine a game app, but in wood. Measures 6” x 3-1/4” x 3/8”, like an iPhone 6-Plus, but you never have to charge it and there’s no glass to break. Has (42) colorful geometric shapes in a wooden frame, and all you have to do is take the shapes out and try to fit them back in again, which is harder than it sounds, but that’s what puzzles are for.

The draw-it-yourself jigsaw puzzle, just begging to have an invitation written on it, and then be mailed to potential guests as a handful of pieces. But this 28-piece cardboard puzzle also measures a desktop or car-friendly 6-3/4" x 4-3/4" in plain white, so it's also begging to have kids add a picture for the fun of it. It's even suggesting that you mix the 336 blank pieces in a pile, explain it's a dozen pictures of an albino moose in a snowstorm puzzle, which it might very well be for all we know, and award a prize for the first finished puzzle. Note the classroom and party-friendly bulk price.

Our each is a standard set of (28) cream-colored, black-divot dominoes, sized 1-7/8" x 15/16" x 5/16" thick. Includes a wooden case and a tiny sheet with the rules for Double-Six, one of the endless popular domino games.

Numerate, are you? Find out with these Ninja Assassin Sudoku books of (248) puzzles--(2) per page, plus solutions--in 176-page paperbacks. You pick the White Belt (entry-level to medium), Yellow Belt (easy to easy-medium), or Green Belt (easy-medium to hard-medium). By Frank Longo from Puzzle Wright Press. Best part is you can ignore the $6.95 cover price.

Half of the best stuff in the world comes in a can; the other half comes on a stick. (It’s true, don’t argue with us.) Now you get to pick from two kinds of canned fun, both in 5-5/8” x 4” x 2-1/4” deep cans with hinged tops. You pick. The Pranks in a Tin has straw finger traps, a whoopee cushion, nose & mustache glasses, a joy buzzer, the nail-through-finger trick with a bloody bandage, and a squirting ring. Go make a pre-adolescent happy. The Classic Games tin holds a standard deck of playing cards, rubber ball and (10) metal jacks, tiddlywinks with a small felt pad, (30) pick-up sticks, and (5) shooters plus (30) smaller glass marbles, and not an electronic game in the bunch.

Fluxx®, the card game with rules that change while you play, has gone chemical. Cards feature your favorite elements, released from their table at last, plus sundry lab items. Includes our new favorite rule: draw the Helium card and you must speak in a falsetto voice.

It's nice to know that some things don't change. One is the Jacob's Ladder. Still made with (6) slabs of wood, each about 2" x 2" x 1/2", each a bright combination of colors, and all connected by a contrasting ribbon. Hold one end up and let the string of slabs dangle. When you flop the top block end for end, each lower slab in turn will flop end for end. Fascinating. Particularly if you are about 5 to 9 years old.

Now comes this ball of geometric possibilities, from creativity guru Roger von Oech. Perfect for anyone with a 3-dimensional mind, from a precocious child to a bored nonagenarian, including your favorite artist, mathematician, designer, engineer, or whatever. The little red ball, 3-1/4" dia, comprises (30) magnetized right golden rhombic pyramids that will fit together in endless shapes, from a rhombic triacontahedron (see the pic), to stars, wreaths, animals, sunbursts, and endless others. Comes with a 96pp booklet on geometric possibilities and creativity. Plenty of desktop noodling fun, but a lot more than just a toy.
