BugTales
Every character has one recurring bug. Read the program they submitted, mark the line that is wrong, then reveal the fix and write the bug report — the real debugging loop. A read-to-debug coding lab. Ages 9–14.
▶ Play it nowBuilt for sittings of about 20 minutes on the screen. That is our design budget, not a measurement.
Meet your mentor
Every Spark & Anvil app has a friendly mentor character that demonstrates, asks, and patiently scaffolds learning.

Meet the cast
BugTales's ladybug coders each make one bug every time: you read their program, find the line, and write the bug report.
Offby
(A ladybug) - always stops one too soon or goes one too far
Equals
(A ladybug) - says make this equal when it meant is this equal
Andor
(A ladybug) - wants both things but asks for either one
Range
(A ladybug) - reaches for an item that isn't there
Zero
(A ladybug) - tries to share something into zero groups
Hush
(A ladybug) - runs with no error but quietly gets the answer wrong
Forever
(A ladybug) - goes round and round and never stops
