Almost everyone knows it and has certainly played it before. Sudoku is a logic game that is usually played on paper and with the numbers 1 to 9. Coldoku, on the other hand, is a great variation of the classic Sudoku. The main difference is that colors and shapes are used instead of numbers. The aim of Coldoku is to place the playing cards in such a way that each color and shape appears only once in all rows and columns. Coldoku is a brain game for children, teenagers and adults.

Verdict
The clearest difference is review sentiment: Coldoku at 100% against Collect2Merge's 0%. Coldoku also leads on ads (none vs shown) and monetization model (free vs ad-supported). Collect2Merge's advantage is update cadence (fortnightly vs every 6 weeks) and iOS requirement (11.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.
