## Difficulties
For the current implementation, we just use Legacy. Which is actually kinda cool because you'll be surprised.
- Legacy: hole positions + minBound (aka, try 50, see what you get)
- Crude: targeted range of holes + minBound (aka. 32-35 holes)
- Graded: rank techniques and dig as much as grade allows
- Balanced Grading: Complexity score which allows several harder rank holes
- Hybrid Grading: Rank techniques + bounds
### Grading Techniques
#### Beginner
You can directly put a value
- Last cell in row
- Hidden singles
#### Very Easy
You can directly exclude a value, leading to a value
- Direct pointing
- Direct claiming
#### Easy
You can exclude a value, narrowing down possibilities
- Pointing / Naked Pairs
- Claiming
#### Medium
You can exclude a value based on (double) superposition
- X-wing
- Hidden pairs
- naked triplets
#### Hard
Triple superposition
- Swordfish
- Hidden triplets
- Skyscraper
- etc..
#### Very Hard
lots of holes
- complex, partial trial and error
#### Impossible
as much holes as possible
- brute force probably required
Anyways for now we stick with Legacy Difficulty.
