Many Indian players grew up with paper lottery tickets. In an online casino, though, "lottery games" means something different: fast keno and bingo-style games where numbers are drawn by a random number generator (RNG) or a live ball machine. This guide explains how the main lottery-style games in Betroxy's lottery games lobby work: Keno, Mega Ball and EZ Bingo 90, with the rules and the return-to-player (RTP) figures the providers publish.

How keno works
Keno is the closest casino game to a classic lottery. You choose your numbers (called spots), set your stake, and the game draws a fixed set of numbers. Your payout depends on two things: how many numbers you picked and how many of them were drawn. Each provider has its own paytable, and the paytable inside the game is the one that counts.
Spribe Keno
Spribe's Keno uses a small board of 36 numbers. You pick up to 10, and 10 numbers are drawn each round. Spribe lists an RTP of 97%, the highest among the games in this guide. A quick-pick button can choose numbers for you, and the game menu includes provably fair settings for checking past rounds. Our fairness page explains how game results on Betroxy are decided.
Because 10 of the 36 numbers are drawn, any single number you pick has a 10 in 36 chance (about 27.8%) of coming up. Hitting every number is far harder: if you pick 5, the chance that all 5 are drawn is about 1 in 1,496. If you pick 10, the chance of matching all 10 is about 1 in 254 million.
Play'n GO Keno
Play'n GO's Keno, first released on 24 October 2012, is the traditional version: an 80-number grid, 20 numbers drawn per round, and 2 to 10 picks. Each number you choose has a 20 in 80 (25%) chance of being drawn. Picking 5 and hitting all 5 happens about once in 1,551 rounds on average, and 10 out of 10 is roughly a 1 in 8.9 million event. Play'n GO notes that the minimum number of hits needed to win depends on how many numbers you select. Sources disagree on this game's RTP, so check the figure in the info panel before you play.
A third keno game, from ICONIC21, sits in the same lobby. Read its paytable separately, because board size and payouts vary between providers.
Mega Ball: bingo cards with a multiplier
Evolution describes Mega Ball as a lottery-style game. It plays like bingo:
- You buy between 1 and 400 cards. Each card is a 5x5 grid with 24 numbers and a free square in the centre.
- 20 of 51 numbered balls are drawn. Matching numbers are marked on your cards automatically.
- Every complete horizontal, vertical or diagonal line of five pays. One line returns your stake, and more lines on the same card pay more, up to 9 lines per card.
- After the main draw, one or two Mega Balls are drawn, each with a random multiplier from 5x to 100x. If a Mega Ball number completes a line on your card, that card's payout is multiplied.
You can play it in two ways. First Person Mega Ball is the fast RNG version, and Mega Ball is the live version with a real ball machine in a studio.
Evolution's rules give an optimal RTP of 95.40% when you play one card, with a range of 94.61% to 95.40% depending on how many cards you buy. The rules also say the top prize (6 or more lines with an exact 100x multiplier) has a chance of about 1 in 13.4 billion on a single card. Buying more cards raises your chance of a line in each round, but it also raises the cost of every round by the same amount. For example, 20 cards at ₹5 each cost ₹100 per draw.
EZ Bingo 90: live 90-ball bingo
EZ Bingo 90 is Ezugi's take on traditional 90-ball bingo, hosted by a live presenter. Each ticket carries 15 numbers in three rows, numbers from 1 to 90 are called, and your tickets are marked automatically. Prizes go for completing one line, two lines and a full house. Ezugi says standard rounds take around four to five minutes, so the pace is slower and more social than keno.
Game listings put EZ Bingo 90's RTP at 87%, well below keno or Mega Ball. You can find it with the other live draws in the live lottery section.
The lottery lobby also includes bingo-themed titles from Play'n GO (Tome of Madness Bingo, Rise of Olympus Bingo and Piggy Heist Bingo), BGaming's Jogo do Bicho, based on Brazil's traditional animal lottery, and First Person Dream Catcher, a money-wheel game covered in our Dream Catcher guide.
Casino lottery games are not state lotteries
In India, paper lotteries run by state governments, such as Kerala's, fall under the Lotteries (Regulation) Act, 1998. Casino keno and bingo are different products: they are short games with a fixed house edge, run by game studios, and they have nothing to do with any government draw. Results from a state lottery, or from an earlier keno round, tell you nothing about the next draw.
What the RTP means in rupees
RTP is a long-run average over a huge number of rounds, not a promise for one session. Still, it shows how much a game keeps over time. On ₹10,000 of total stakes:
- at 97% (Spribe Keno), the theoretical return is ₹9,700;
- at 95.40% (Mega Ball with one card), it is ₹9,540;
- at 87% (EZ Bingo 90), it is ₹8,700.
Tips before you play
- Read the paytable and info panel first. They show the RTP for that version, the stake limits and the maximum payout.
- Set a budget per session. On a ₹1,000 budget, ₹10 keno rounds give you at most 100 rounds. Keno rounds are quick, so a budget can go fast.
- Ignore "hot" and "cold" numbers. Every draw is independent. A number that has not come up for a while is not "due".
- Avoid predictor apps. No app or Telegram group can predict an RNG draw. Many of them are scams designed to take your money or your login details.

Online lottery games FAQ
Which lottery-style game has the highest published RTP? Among the games here, Spribe Keno lists the highest RTP at 97%, followed by Mega Ball at 95.40% for one card. EZ Bingo 90 is listed at 87%.
How many numbers should I pick in keno? There is no best number. Fewer picks give more frequent, smaller wins, and more picks give rarer, bigger ones. Pick what suits your budget and check the paytable.
Does buying more Mega Ball cards improve my odds? More cards give you more chances of a line in each round, but every card costs the same, so your total stake rises too. The RTP is highest with one card.
Is online keno the same as a state lottery? No. State lotteries are run by state governments. Casino keno is a game with a fixed house edge, and each round is decided by an RNG.
Is it legal to play online lottery games in India? Rules on online real-money games differ from state to state and have changed in recent years, including a central online gaming law passed in 2025. Check the rules that apply where you live before you play.
Play responsibly
Lottery games are entertainment, not a way to earn money. Set a budget and a time limit before you start, take breaks, and never gamble with money you need for rent, bills or essentials. If gaming stops being fun, use the deposit limits, short breaks and self-exclusion options on our responsible gambling page. 18+ only.
