Lottorino Scoring Engine is Catchalotto's colour-coded advisory system that assesses the randomness of a combination and consequently the likelihood of a combination being drawn.
It is built on logical deduction and observation of all past official UK National Lottery draws and on the concept of randomness. Every time you submit a combination, it will be driven through various Lottorino filters (a.k.a rules, ranges, criterias) and will be assigned a score depending on how much your combination deviated from the norm (the norm being the most frequently occurring combination(s) in the past and/or the set of rules that define “randomness”).
| Colour | % | Description |
|---|---|---|
| 70% - 100% | Combination passed most or all filters and is considered to have good chances of being drawn. | |
| 50% - 69% | Probability of combination is lowered as minor deviation from the norm has been detected. | |
| 30% - 49% | Combination stands less than 50% chances of being drawn as it failed some of the fundamental rules as set by Lottorino. | |
| 10% - 29% | Combination is considered to be less efficient as it did not pass majority of the rules. | |
| 0% - 9% | Combination is considered to be the least probable as it violated the rules set by Lottorino Scoring Engine, e.g. a strong deviation from the norm was observed. |
If a combination scores 90%, for example, it should be interpreted that such combination has a 90% fit with the patterns set by Lottorino Scoring Engine and thereby stands good chances of being drawn. It is important to remember that there could be other combinations that equally fit into the same patterns, thereby also scoring 90%. It is a mistake to think that you have 90% guarantee that this combination will pop up at the next draw.
To increase your chances of winning, you are advised to reselect your combination should it have a low Lottorino (reselecting only one number may prove to be sufficient). As a rule of thumb, we advise that you reselect your combination if it scores less than 50% (please see Important disclosure below).
Lottorino Scoring Engine contains hundreds of filters which are kicked off every time a combination is verified for its likelihood of being drawn. In general, all filters can be categorised into 2 types: generic filters and filters that are dependant on the last few draws. Generic filters are fairly static (i.e. only updated once a year or when a major change in pattern is observed), whilst dependant filters change every time a draw takes place.
Because of dependant filters, the same combination may have one score today and another score, say, next week. Example of a generic filter is, for instance, a filter that states “if a combination has all 6 numbers divisible by 7 then assign a low score”. This filter will only change should a few combinations containing all numbers divisible by 7 be drawn (even then the score of such combination will not increase significantly as this combination is not really that random). Example of a dependant filter is a filter that states “if sum of all numbers of a chosen combination equals the sum of all numbers of the combination most recently drawn then assign a low probability score”. So if the numbers recently drawn were: 2-8-10-31-46-48 making the sum of its numbers equal to 145, then any combination with the same sum of 145 (e.g. 3-7-11-30-45-49) will have a low score. If you look at the historical UK National Lottery draw data, instances where the sum of numbers of one draw is equal to the sum of numbers of the next draw are quite rare, hence the presence of this rule. Once a draw takes place, combination 3-7-11-30-45-49 would have a different score as the above rule of sums would now have a different sum to consider and will no longer lower the score of this combination.
There are quite a few dependant filters incorporated within Lottorino Scoring Engine, hence there could potentially be a number of combinations that could have one score today and another score next week. By developing Lottorino Scoring Engine, we wanted to eliminate as many combinations as possible so as to increase our chances of winning. Having dependant filters within Lottorino Scoring Engine allows us to reduce even further the list of potential winning combinations that passed generic filters.
If you try to verify a combination drawn in the past it will have a low Lottorino score (<9% probable). This is due to another dependant filter set within Lottorino Scoring Engine that commands the system to assign a low score to any combination drawn in the past as there has never been a case when the same combination has been drawn again in the UK National Lottery.
Lottorino scores of past lottery combinations can be found here: Lottorino scores of previously drawn combinations. As Lottorino Scoring Engine gets updated with new filters and/or scoring methodology, we aim to reissue this list so as everyone has a better view on how accurately Lottorino Scoring Engine makes predictions.
If a combination has a low probability score calculated by Lottorino Scoring Engine you are in no way obliged to reselect such combination, you can proceed and submit your chosen combination. Catchalotto cannot, in any way, be held liable should you reselect your combination only to find out that your initial combination would have won you a greater prize. As before, there is neither certainty nor guarantee. Lottorino Scoring Engine is based on previous official lottery draws and is designed to reflect the most probable scenarios as defined by the past.
Remember in the long run, we should benefit from using Lottorino Scoring Engine. However there certainly will be draws, like there have been in the past, when a combination with a low Lottorino score may prove to be a winning one. As many financial institutions say “beware - past performance is not necessarily a guide to the future”. Similarly, as the rules set within Lottorino Scoring Engine were derived from the past UK National Lottery draw data, the system cannot foresee occasions when a combination may “rebel” and be drawn despite any governing laws.
