Pack & Stack is a game of loading trucks. Every round, you get a random assortment of boxes in different sizes, pick a truck from a random set flipped over, and try to get everything on the truck with as little empty space as possible. You lose points from an initial pool for unpacked boxes and empty space; highest score when someone counts down to 0 wins. The game makes good use of components and simultaneous play, has minimal interactivity, and is strongly subject to randomization. Potentially good for younger players or people who like luck-based games.
The components are good: boxes of five different sizes of colors, dice of corresponding colors with unusual numbers of pips per side, and solid truck boards. In many games, I go with the old idea of having a set of good components to use with many games, rather than whatever cheap pawns, money, etc. come with this box to justify its cost. (I have been using these coins for Seven Wonders, although I think I will be switching all my games’ money to Tech’s new coins.) The components here are essential to the game, well conceived, and of good quality.
Pack & Stack encourages simultaneous play, and if it had more dice, everything could be done simultaneously. You each roll to get your packages one at a time, then all flip trucks simultaneously, then all pack trucks simultaneously, and you can also score losses simultaneously if you trust everyone’s math and honesty. The only interactivity is the dash for trucks, and even then nothing is contested unless two players rolled similar stacks of boxes. Contrast games with no interaction that still officially have everyone acting in play order, or Seven Wonders with simultaneous play and some interaction.
Pack & Stack is mostly a luck-based game. Assuming that you have basic spatial relations skills and can perform single-digit arithmetic, you have all the skills needed for mastery, which you will achieve within five minutes. The one meaningful decision you make each round is which truck to pick, and unless the perfect truck is randomly available, your decision is arithmetic plus least bad choice. If you are on board with my contention that interesting decisions are the fun of gaming, this is not for you. If you like slot machines, this will be an exciting step up in your gaming; you even start with a pool of points and try to be the furthest from zero at the end, so it is like sitting next to your friends at the slots, pulling the bar to see how much you lose this time, and continuing until someone runs out of money and you leave. But you get to arrange little boxes on a truck, which is somewhat more fun than watching the game play itself.
Obviously not something I’m going to play again, but it has a few good uses of rules and could be attractive to some audiences. Its rules fit on a page, not in a book, and the game is not language-dependent, hence my thinking “good for kids?” (old enough not to try to swallow Legos).
