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.
Was this fun?
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.

Controls

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.
