Your mileage may vary
There is no other table-top game that consumes more of my time than Rummikub. I find it very addicting.
However, your experience may vary depending on the version. I had the version with "easy-grip contour" pieces. After a lot of play, the paint has chipped away to the point that many pieces are unreadable causing me to need to buy a new set. This is not a problem with the editions with engraved pieces.
BUYER BEWARE: I ordered this set from Amazon because it said that it had engraved pieces. The version I received though did not. If you look at all of the pictures for this product, you can see that many different versions are represented. I assure you, they are not all created equal.
