Verdict
The clearest difference is in-app purchases: Image Slide Puzzle at none against CoKu's 3. Image Slide Puzzle also leads on update cadence (every 3 months vs every 7 months) and ratings volume (16 vs 3). CoKu's advantage is ads (none vs shown) and rating (5.0 vs 4.6). On price, review sentiment and device support there is nothing between them.
