Untuk memainkan scratch dibawah kamu bisa:

klik bendera untuk mereset ulang
klik sprite untuk menambah nilai dari sprite tersebut

kamu bisa membuat:
clover->klik gambar clover
coin->klik clover 2x lalu klik coin
ruby->klik clover 4x lalu klik coin lalu klik ruby
crown->klik clover 5x lalu klik coin lalu ruby lalu crown
cat->klik clover 11x lalu coin 3x lalu ruby 2x lalu crown lalu cat

kamu tidak bisa membuat sprite jika bahannya kurang, contoh:rubi butuh coin dan dua clover.
sprite akan hilang setelah dirubah menjadi sprite lain.
