Orixo from last year? The Logisk Studio has a sequel called Orixo Wormhole. The object is to fill the entire grid by sliding the numbered tiles according to their values. This is a very polished game. The graphics are crisp & colorful. The challenges are fun. The price is right too. Though there are ads.
There are 128 Medium levels. Again, I did half.
There are 64 Expert levels. At the moment I've done 45.
There are 32 Insane levels. I've done a few.
