Digit Drift

A banner tells you what to catch right now, bigger than 50, prime, even, and so on. Numbers fall through the lanes; move your catcher beneath the right one and grab it. Every correct catch chains a brand-new rule, while a wrong catch drains your fuel.

• Catch numbers matching the current criterion to score and chain.
• Wrong catches cost fuel; run out and the game ends.
• Fuel acts as your streak buffer, so accuracy keeps you alive.
• The rule changes after every successful catch, read fast.

• Desktop: move with ← →, catch with the Space bar.
• Phone & tablet: tap a lane to move the catcher there and grab the number in it.

• Daily seeded fall or endless Practice.

• Scan all the lanes before committing, only one falling number usually fits.
• Let a wrong number drop past rather than grabbing it just because it is closest.
• Build a fuel cushion early so a single mistake later does not end the run.

Digit Drift turns falling-number catching into rapid practice with primes, parity and comparing values, training quick number judgments.

• Skills: primes, parity (odd/even), comparing numbers, number sense
• Best for: roughly grades 3–6 (ages 8–12)
• For parents & teachers: quick number-property reflexes, gamified.

Catching only the numbers that satisfy a banner rule — bigger than fifty, prime, even — is classification by number property, the same skill the muncher games drill.

The original mechanic is that every correct catch chains a brand-new rule immediately.

Constant rule changes prevent the one strategy that makes these games hollow. If the criterion holds for a whole round you can stop reading it and pattern-match; replacing it on every success means the banner has to be re-read each time, which is the actual exercise.
