How to play
Make five choices. Read one result.
- Choose exactly five different numbers from 1 to 40 and an amount of free points.
- Select Draw ten numbers. Ten different numbers are drawn uniformly from the forty. Each round uses a fresh full set.
- Match your five choices against those ten. The fixed table below gives your total return, including any points played.
No automatic draws, bonus rounds or extra charges. Zero or one match returns nothing; two matches returns your points for a net change of zero. Change your choices between draws. End play stops new draws for this browser session; saved results stay readable.

Any set of five has the same probabilities: C(5, k) × C(35, 10 − k) / C(40, 10) for k matches. The mathematical average total return is approximately 93.008% of points played over all possible draws; it does not predict your session or guarantee a return. These are free points with no cash value.
