Help for ohell scoring

You must take exactly the number of tricks you bid to gain points when scoring. 
If you take any more or either fewer or more than your bid, you lose points.

If you make your bid, you gain 10 points plus your bid squared. So, making a bid
of 6 is worth 46 points. If you bid zero and make it, you gain 10 plus the 
number of cards in the round. So, a successful bid of 0 in round 4 is worth 14 
points.

If you fail to make your bid, you lose the cube of the difference between your 
bid and the number of tricks you take! So, being off by 1 only costs you one 
point. However, this grows quickly. If you bid 5 and make only 2, you lose 27 
points.

It is almost always better to make a 0 bid than to make a 1 bid. However, it is 
more dangerous, as being forced to take any trick will make you miss your bid.

Also, remember: it is just as bad to take too many tricks as to take too few.
