Typefi Thermo: Can you crack it?
Ever played a cryptic sudoku?
In the early days of the 2020 COVID-19 lockdowns, several members of Typefi’s Australian team became addicted after discovering The Miracle Sudoku, a weirdly compelling viral video of a puzzle-master sitting in a gloomy English attic solving a sudoku with just two given numbers.
As it turns out, there are many ‘cryptic’ variations on the classic sudoku. Ben “Baz” Vale, Typefi Senior Engineer, recently decided to take his sudoku obsession one step further by setting these challenging puzzles himself.
So, from the mind of Baz, we present Typefi Thermo. Can you crack it?
(The linked puzzle also contains a ‘Solve’ option, but if you’re having trouble getting started, we recommend checking out the rules and hints below first.)
The normal rules of Sudoku apply—each row, column and square (9 spaces each) needs to be filled out with the numbers 1-9, without repeating any numbers within the row, column or square.
If you’ve never played sudoku before, you can find basic instructions and solving techniques at masteringsudoku.com.
In the Thermo Sudoku variant, ‘thermometers’ are overlaid on the grid. Numbers in the thermometer sections must increase in value from the bulb end (the numbers do not need to be consecutive).
Trouble getting started? Click below to expand the hints.
Start by filling in the upper thermometer (the horizontal part of the Typefi ‘T’). Remember, the numbers must increase from the bulb ends.
As the upper thermometer is nine squares and the numbers inside it must increase from the bulb ends, the thermometer MUST contain the numbers 1-9.
