Many of the examples from the block sets which provide such things provide not just marketing examples or construction encouragement, but also provide some degree of challenge as the builder attempts to figure out how the construction actually goes together.
Sometimes that is inadvertent, but sometimes as with MindWare's Blik-Blok, the block building challenge is the actual purpose of the set. One is given an example. ala Tangrams, and told what pieces to use to build it. The solution is on the back of the card.
Unfortunately, concept doesn't live up to implementation in my Blik Blok set, but it is dated 2006, and maybe Mindware has corrected the plethora of errors in the cards, maybe Mindware has corrected the poor sizing and quality of the blocks.
Even if they have, I think I would prefer Foxmind's Architecto, the subject of my next post.
If you absolutely must have wood, instead of Architecto's high quality & extremely accurate plastic, you might want to choose Blik Blok. Otherwise, I only recommend it for those who want both and are willing to struggle past the problems.
One might note also that the cards aren't numbered. Numbers are useful in the classroom, and their absence stopped me from listing errata.
You do get more designs, and more different block shapes - though both of which may will convince you that more is not necessarily better, though they ARE interesting, in a way.
At its worst, Blik Blok is irritating.
But at its best, it is Good Block Play.
