Gakken are probably one of the most popular “waffle” blocks. The Gakken Blocks sets have many different forms and shapes of the blocks. There are arched blocks, blocks with different numbers of pegs on different sides, and figurines. There are also some pieces that can work like the rails for the Gakken trains. That same pieces are just as thick as any other Gakken blosk, and you can use them in many ways, not just for building rails.
Gakken are Japanese sets, and Japanese Amazon have bigger choise of them. But the shipping may be long and expensive. In countries that are far from Japan, finding these sets can be more tricky, but there are plenty of sets that have pieces of the same shapes.
Original Gakken Blocks sets were invented in Japan in 1960s. They original purpose was education and helping children develop imagination and fine motorics. Gakken quickly became popelar in Japan, and they are one of the oldest “waffle” blocks that are still around. There are many sets that try to repeat Gakken concept, but not all of them have this high quality. Another similar set brand is Danish Plus Plus, but in Plus Plus all the pieces have the same shape.
