2D Lotto Draw Sum
The typical 2D Lotto draw sum over the last 20 draws: average — 27.4, the most common sum is 32, range from 7 to 46.
median — 27 (half of the draws landed below it), spread between the records — 39.
A draw sum is all the drawn numbers added together. On the chart below every point is one 2D Lotto draw: clicking a point marks that draw's numbers on the play field, and the cards under the chart show the average, median and spread.

OpenDraw sum questions
What do 2D Lotto numbers usually add up to?
The archive average is 27.4, the most common sum is 32, and all draws fell between 7 and 46. The exact minimum, maximum and sum of every single draw are collected in a separate table.
What does the sum chart show?
Every point is one 2D Lotto draw and the vertical axis is the sum of its numbers; multi-field lotteries get one line per field. Clicking a point marks that draw's numbers on the play field — handy for seeing what an unusually low or high sum was made of.
How do I build a combination with a target sum?
Picking numbers to hit a sum by hand is slow — the sum generator does it: set a range and it searches for random combinations that land inside it. The default range is already set to the typical values.
Is there an “optimal” sum to play?
There is no guaranteed winning sum: every combination is equally likely. But the middle of the range has a combinatorial property — there are simply more of those sums: an extremely low sum can only be made by a handful of picks from the smallest numbers. That is why winning draws cluster in the middle — just like most possible combinations.
Where can I see the sum distribution and a forecast?
The deep dive into the total draw sum — the distribution histogram, how often each sum repeats, the “which sum follows which” transitions and a heuristic forecast — lives in the extended sum analysis.
