In case you haven’t been keeping an eye on Invisible City lately, you might want to check their free games page. They’ve just released a pair of trick-taking games for your amusement: Hidden Rules, a Mao-inspired affair in which different players know different rules to the game, but nobody knows everything; and Birthday Party, Cheesecake, Jelly Bean, Boom!, which puts a simple yet distinctive twist on the venerable form. Sometimes it’s nice to take a break from the complicated stuff and just play cards; this is a good excuse.
