Gotcha Cat← Back to the gameTake a photo, change 3 to 7 details, solve it yourself once, and send the link to your friends. Free.
Your cases are saved to your account. Making cases is for players aged 16 and over; playing a case from a link needs no account.
Best: a room, a desk, food, a garden, a pet, a street — lots of small objects. No people or children in the picture.
Pick a tool, then tap the picture where the change should be.
Next you solve your own case once — then its link works for your friends.
