Unlimited Tango, no daily cap
The daily puzzle is one board a day. This page is the opposite: pick a difficulty and play as many Tango boards as you want, one after another. Nothing to sign up for, and your streak on the daily board is never affected by practising here.
What the difficulties mean
On a six by six grid the solving techniques barely change, so what actually makes a board harder is how much you are given to start with. Fewer starting numbers means longer chains of reasoning:
- Easy starts with 18 of the 36 squares filled in.
- Medium starts with 14.
- Hard starts with 10 to 12, so you will be working across the whole grid at once.
Whichever you choose, the board is always solvable by logic alone. We check every one with a solver before it ships, so you never need to guess and there is never more than one answer.
