Route numbers on belts, combine them with math & solve daily factory puzzles!
Route numbers on belts, combine them with math and fill every order. Then build bigger.
Digit Depot is a calm number puzzle and factory game made for your phone. Extract digits from number deposits, carry them on belts and feed them through math machines until a depot gets exactly the number it ordered. Need 228? Add 2 and 3, join a 7 to make 57, multiply by 4. Build it once and watch it run on its own.
Build your number factory
• Draw belts with one finger; corners turn by themselves, and crossing another belt places a bridge for you
• Eight math machines: add, subtract, multiply, divide (with a separate remainder output), join digits, reverse digits, digit sum and square
• Splitters, mergers, sorters (even, odd, prime, palindrome and more), trash and bridges keep the flow tidy
• Tap any number to see the exact recipe that made it
Orders, depots and plots
• Eight depots, each a customer with its own order type: exact numbers, multiples, ranges, primes, palindromes, digit sums, combos and mega orders
• Fill orders to earn coins and level up depots; from level 2 a depot offers a contract that pays for every matching number you keep sending
• New orders often build on the last one, so your factory grows instead of being torn down
• Buy neighboring plots ring by ring to reach new deposits, depots and machines
• Upgrade belt, extractor and machine speed
• Targets start small and climb into the billions
• Every order is generated from a working solution, and a hint is there when you are stuck
A new number puzzle every day
• Everyone gets the same daily puzzle on a fixed board with a limited set of parts
• Solve it with as few parts as possible to earn up to three stars
• Keep your streak going and see how you rank on an anonymous daily leaderboard
• Share your result without spoiling the solution
• Daily rewards bring coins back to your main factory
Made for touch
A factory game designed for fingers from the very first tile.

Comfortable to play
