Game: Skip-Bo and Skip-Bo MOD
Skip-Bo is almost like conjoint Freecell where you are playing with shared supply, discard, and build stacks. You only have control over your own tableau for "hold cards" and proper use of that is the real strategy. There is advanced strategy of watching the other person's tableau in order to they to leave them without being able to utilize/unblock cards (for example, I may play one fewer card at the end of my turn if that card would have allowed you to get cards off your tableau).
Skip-Bo MOD adds a dice roll to each turn and reduces the number of cards needed from 162 to 112. This allows the game to fit into a wonderful travel case. The dice can speed the game up if it's working in your favor by giving you wilds or numbers you actually need to build upon. I keep a set in the car for spontaneous games at the coffee shop or lunch stop.
Has the potential for older kids and adults to play together. Good beginner type game to learn hand management, pre-planning, and learning to pay attention to your opponent to learn strategy.
Moderate to serious gamers will be bored by this. This is more of a card game for fans of traditional cards games, is best with two players, and is probably most enjoyable playing with an AI opponent electronically.
The Verdict: Play, maybe Pass
If you like card games like tableau card games like Soliaire, Freecell, or Spider, and easy hand management/sequential strategy card games like UNO, then Skip-Bo is something you'd probably enjoy. If you bore easy, this will probably best be passed.
iOS: Spite & Malice
Spite & Malice has three levels of difficulty, which really helps you learn basic to advanced strategy to keep up. The Achievements in the game are fun to earn, and encourage that you play all three difficulties. Probably in my top 5 iOS "only have a few minutes to play" games.
