Tens Tower
Climb a tower one floor at a time, paying each toll to the exact ones, tens and hundreds — regroup ten-for-one whenever a place comes up short.
How to play
Each floor demands an exact toll in ones, tens and hundreds. You can only spend a place if you hold enough of it, so when a place is short you must regroup — break one ten into ten ones, or one hundred into ten tens — to make change. Limited holding slots cap how many blocks you can keep, which forces you to bundle small pieces up too. Pay every floor's toll to reach the top.
- Pay each toll exactly across ones, tens and hundreds.
- Break a higher place down to make change when a place runs short.
- Bundle ten of a place up into one of the next to free crowded slots.
- Limited slots mean you must regroup in both directions.
Game modes
- Daily: the same tower for everyone, in Easy, Medium, or Hard.
- Practice: fresh random towers at your chosen difficulty.
Controls
- Desktop: click your blocks and the regroup/pay actions to make the exact toll.
- Phone & tablet: tap blocks to spend them and tap the regroup buttons to break down or bundle up.
Tips & strategy
- Read the toll's place values first, then check which places you're short on before regrouping.
- Bundle up proactively when slots get tight, so a later floor doesn't leave you stuck.
- Fewer regroups score higher — plan the change you'll need rather than breaking down blindly.
