How the lottery numbers are picked in Kerala lottery?

The Kerala State Lotteries is a lottery program run by the Government of Kerala. The Kerala Lottery was established in 1967, under the lottery department by the Government of Kerala, with the objective of providing employment and support to the financially backward people of Kerala.

The Kerala State Lotteries Department conducts seven weekly lotteries and six bumper lotteries every year. The seven weekly lotteries are Pratheeksha, Dhanasree, Win-Win, Akshaya, Bhagyanidhi, Karunya, and Pournami lotteries. The bumper lotteries include Xmas, Summer, Vishu, Monsoon, Thiruvonam, and Pooja/Dussehra bumper lotteries.

The lottery draws are conducted at Gorky Bhavan near Bakery Junction, Thiruvananthapuram under the supervision of independent judges. Lottery draws are conducted on a daily basis for the seven weekly lotteries at 3:00 PM Indian Standard Time. The six bumper draws are conducted occasionally on special days like Christmas, Onam, Vishu etc.

The Kerala lottery system follows a very transparent mechanism for conducting the draws. The draws are conducted in front of the public and media houses. The lottery numbers are selected using a random number generation process which ensures that the draws are completely fair and random.

How are the Kerala lottery ticket numbers generated?

The Kerala lottery ticket numbers are generated through a highly randomized process that utilizes advanced cryptographic techniques. Here is an overview of how the lottery ticket numbers are generated:

1. Selection of lottery sets

For each lottery draw, multiple ‘sets’ or ‘series’ of ticket numbers are released. For example, for Akshaya lottery, AK-457-1234 and AK-458-1235 are two different ticket series. Each set has around 1 lakh tickets which contain unique 6 digit numbers from 000000 to 999999.

The Lottery department randomly selects the sets that will be used for a particular draw. This is the first step in introducing randomness into the number generation process.

2. Mapping tickets to prize levels

Once the sets are selected, the next step is to assign the prizes to the tickets. There are multiple prize levels in each lottery draw – first prize, second prize, third prize and so on.

Each set of 1 lakh tickets are randomly mapped to the prize levels by the automated system. For example, in a 1 lakh set, 1 ticket may be assigned the first prize, 3 tickets second prize, and so on. This mapping is done separately for each set.

3. Randomization using cryptography

Now each ticket has a set number and a prize level assigned. But the tickets still need to be randomized within the set to remove any patterns.

This is done using cryptographic random number generators and hash functions. Each ticket number is passed through cryptographic one-way hash functions to generate encrypted numbers. Then a CSPRNG (Cryptographically secure pseudo-random number generator) is used to shuffle the encrypted numbers randomly.

Finally, the shuffled numbers are mapped back to the original ticket numbers. This cryptographic randomization ensures that the ticket numbers are randomly mixed up while still retaining the set number and prize level mapping.

4. Printing lottery tickets

The final randomized ticket numbers along with the set number, serial numbers and prize level details are sent to the printing press for printing.

This entire process ensures that the lottery draw process is fair, random and transparent right from ticket printing to prize announcements.

How are the winning numbers selected in each draw?

The process of actually selecting the winning numbers for each draw also follows a highly secure and randomized process:

1. Selection of sets for the draw

For each draw, the sets of ticket numbers to be used are randomly selected. The selected sets are the ones eligible for the particular draw.

2. Winner selection through draw

The draw is conducted in front of judges and public representatives. A random number generation process is used to select the winning ticket number from the eligible sets for the draw.

Earlier, physical methods like using rotating drums were used. Nowadays, most lotteries use computerized random number generators for the draw.

3. Prize level matching

Once the winning number is picked, it is matched with the preassigned prize levels in the selected sets to identify the prize won.

For example, if the winning number was from a set mapped to the first prize, the winner gets the first prize.

4. Announcing results

The results are immediately announced and conveyed to the public through official channels and media. The winners can submit their tickets to collect the prize amounts.

The selection of sets for the draw and the winner selection process are handled securely by the lottery officials. The computerized RNG systems are subjected to thorough testing and auditing to ensure fairness. The physical draw process also has multiple scrutiny levels. This ensures public confidence in the system.

What is the probability of winning the first prize?

The probability of winning the first prize in Kerala lottery draws depends on several factors:

1. Number of ticket sets selected for the draw

More sets means more number of tickets eligible for the draw, lowering the odds of winning. Typically, 20-40 sets are selected with around 20 lakh tickets.

2. Number of first prizes assigned

Usually, there is only 1 first prize winner per set. With 40 sets, there will be 40 first prize tickets.

3. Total tickets in the draw

With 20 lakh tickets across 40 sets and 40 first prize tickets, the probability is:

Probability = Number of first prize tickets / Total tickets

= 40 / 20,00,000

Which equals 1 in 50,000 probability of winning the first prize.

The more the number of tickets and sets, the lower are the odds of winning. But the prize money is also distributed across more winners. Recently, Kerala lottery draws have seen lower number of tickets, improving the odds for each participant.

Do lottery ticket numbers matter?

Since the Kerala lottery draws follow a randomized system, all tickets within a set have an equal probability of getting picked in the draws. The ticket numbers are for identification purposes only and have no influence on the chances of winning.

However, certain ticket numbers are considered ‘lucky’ by some people and there is higher demand for tickets containing these numbers. Some of the frequently played ticket number combinations are:

Consecutive numbers

Numbers in an unbroken sequence like 12345, 56667 etc. Some people believe getting sequential numbers brings luck.

Birthdates or anniversaries

Important dates and numbers related to a person like birthdays.

Number patterns

Tickets where numbers form a familiar pattern like 123321, 55555 etc.

Lucky numbers

Numerologically significant numbers like 786 or culturally auspicious numbers.

Repeated single digits

Numbers with only one repeating digit like 111111, 777777 etc.

However, ticket numbers have no logical bearing on winning odds. The randomized pick process makes all numbers equally likely. But people still prefer certain combinations based on personal beliefs and superstition.

How are lottery prizes given out?

The Kerala state lotteries have a systematic process for distribution of prizes won in the lottery draws:

1. Prize claim process

Winners have to submit the physical lottery ticket at an authorized lottery office. Certain verification checks are done to validate the winner.

2. Prize amount limits

Smaller prizes up to Rs 5,000-10,000 can be claimed from district lottery offices. Bigger prizes must be claimed from the Directorate in Thiruvananthapuram.

3. Prize distribution

Up to 30% of the prize is given in cash. The remaining amount is given through cheque or direct transfer to the winner’s bank account.

4. Taxes and deductions

Income tax and other statutory deductions are made as per Kerala government rules before disbursing the prizes.

5. Unclaimed prizes

Unclaimed prize amounts are held up to a year by the lottery department. After that, the unclaimed amounts are used to create a welfare fund for economically weaker lottery buyers.

The Kerala lottery system has effective administration and monitoring to ensure all prizes are disbursed properly to the rightful winners. The prize claim and tax deduction processes are also streamlined.

What is the amount of the first prize?

The first prize amount varies across the different Kerala lottery draws. Here are the typical first prize amounts for major lotteries:

Lottery First Prize Amount
Akshaya Rs. 70 lakhs
Karunya Rs. 80 lakhs
Pournami Rs. 70 lakhs
Win Win Rs. 75 lakhs
Christmas bumper Rs. 12 crores
Onam bumper Rs. 12 crores

The first prizes usually run into several crores for the bumper lottery draws conducted during major festivals. The prize amounts are fixed in advance while announcing the lotteries.

Are lottery winnings taxable in Kerala?

Yes, lottery winnings above a threshold are taxable in Kerala as per central and state tax laws:

Income tax

Winnings above Rs 10,000 come under income tax. 30% tax is deducted at source for lottery income above Rs 10,000.


28% GST is applicable on lottery winnings. It is deducted at source before disbursing prizes.

State GST

An additional state GST between 1-2% also applies on lotteries. This is over and above the standard 28% GST rate.


A state surcharge of 5% is also levied on lottery winnings in Kerala.

After deducting all the applicable taxes, the remaining prize amount is disbursed to the winner by cheque/bank transfer. Winners may still need to pay additional income tax if they fall under higher tax brackets.

What is the minimum age to play the Kerala lottery?

The legal age to participate in the Kerala lottery draws is 18 years and above. Minors below the age of 18 are prohibited from purchasing lottery tickets or claiming lottery prizes as per Kerala lottery rules.

Some of the regulations are:

1. Age verification

Lottery ticket sellers must verify the age of buyers by checking ID proof before selling tickets.

2. Ban on minor participation

Minors are legally barred from participating in lotteries either directly by purchasing tickets or indirectly through others.

3. No prize claim by minors

If a minor does end up with a winning ticket, the prize claim has to be made by an adult guardian only on submitting age proof documents.

4. Seller penalties

Selling agents face suspensions and cancellations for violating the minimum age restrictions. It can also lead to their lottery license getting cancelled.

The age restriction of 18+ is a firm rule across all Kerala state run lottery draws. It aims to prevent underage gambling and addiction.

What is the Kerala lottery tax revenue used for?

The Kerala state government earns significant tax revenues from lottery ticket sales. This income is used to fund various public welfare schemes and infrastructure development projects across the state.


A portion of lottery proceeds goes towards upgrading hospitals, mobile clinics, free medicine distribution etc. aimed at low income groups.


Funds are allocated for building schools, supplying free textbooks/uniforms, student scholarships and digital education programs.

Social welfare pensions

Lottery money helps provide monthly pensions of Rs. 1600 to disadvantaged sections like elderly, widows, disabled etc.


Public infrastructure like roads, water projects, public housing is created using lottery funds.

Prize money

The prize amounts for the lottery draws are also paid out from ticket sale proceeds. Bigger prizes means more sales.

While boosting state revenues, the lottery system also aims at social justice by funding projects that benefit the common man. The high tax on lotteries allows significant money to be channeled into public welfare.


The Kerala state lottery system follows a meticulous and scientifically designed process for generating lottery numbers and picking winners. Sophisticated cryptographic techniques are used to introduce true randomness at each stage and ensure total fairness. Transparency is also maintained with public participation in the draws. Though some ticket numbers are considered luckier, mathematically each number has an equal chance of winning. The lottery revenue is used for funding development and welfare across Kerala making it a responsible source of state income.
