TanZen HD 4+

This is my favorite bedtime activity. Most puzzles are easily solvable, but some are really challenging. I’ve seen criticism about wanting the pieces to snap into place, but if that were the case, the puzzles would solve themselves. Actually, I like the simplicity of the entire app—no blinking ads, no trickiness to push spending, no clutter. You can purchase colors, but that’s just esthetics. Another good feature—you can actually listen to podcasts or carry on conversations while playing.

LWBS has the best Tangram type game in the App store market. Lots of polish behind the scenes that make the puzzles a joy to play over and over again.

My only downside after multiple playthroughs is I wish there were even more puzzles.

You will while away many hours solving these and the support is great. Recently upgraded to 64 bits to be compatible with 64 bit only OS coming from Apple.

I’ve a knack for these things. I do them quite quickly. Still well worth the paid version. But there’s a flaw. Once I completed the final puzzle, the whole thing locked up and began flashing psychedelic patterns and colors on my screen! The only way to stop it was to force close the app as it won’t respond to touch. Reopening the app appears fine, but only by deleting and reinstalling can you start over again.
