It doesn't exept the correct answer. The 1st is 4 but it says wrong

★☆☆☆☆ Fathia Atanda · Mar 15, 2024

I find it confusing to play. Tutorial guide to put you through on how to go about it isn't on the app. It's so confusing, even the hints aren't helping. I wonder how it has good reviews when you can't play it

★★☆☆☆ Musa Mutombo · Feb 6, 2024

Some question her just hard to find It's because the game is just like a gue game

★☆☆☆☆ REDEEMER SICHIMATA · Oct 16, 2025
