Bit Garden
Hina runs a rooftop greenhouse in Karachi. Every sprinkler, grow light and fan is one bit in an 8-bit register. Set the bits right and the garden does what you meant.
How it works
Each job is one task from the syllabus. Bit 7 is on the left and bit 0 is on the right, with the place value under each bit.
- Tap a bit to switch it between 0 and 1. Its sprinkler, light or fan switches too.
- Type a number with the keypad on the page.
- Choose an operation (AND, OR, XOR) and tap the bits of a mask, then Run it on the register.
Press Check. If it is wrong, you see what the mistake usually is, and the same kind of task comes back as a quick check two jobs later.
Win the First try medal by getting a job right at the first check, and the Quick medal by finishing inside the time shown on the job (the clock starts at your first tap). Play a job again for new numbers.
The greenhouse
One bay for each course. Every pot is open: start with your own course, or jump to any job. A finished job grows a flower.
