Tengi, which gives away half of its advertising income in a free draw every Friday night at 7pm, usual has a £1,000 top prize and hundreds of £25 and £5 winners. It's given away over £100,000 already, in its first few weeks.
But now, in a unique super draw which will take place from now until Friday, February 26, the first prize is £10,000.
Which means Tengi is really living up to its name, pronounced Ten 'G', or 10 Grand.
Neil Laycock, CEO of Tengi, based at the University of Sheffield Bio-incubator, a new business start-ups building, in Leavygreave Road, said: "It's big news here at Tengi. We’ve just announced our first super draw, with the lucky winner taking home £10,000!
"This draw is different and replaces the usual weekly £1,000 draw. It will be over a two week period finishing on Friday, February 26. And we're giving users a huge 16 tickets for every friend that joins, which is up from 10 in the last draw.
"The objective is a push for growth, to get as many people to join Tengi as possible.
"Our marketing/PR and awareness campaign is also up and running - details can be found on our blog - so there has never been a better time to invite friends onto Tengi and make it your chat app of choice!

Why would you use Whatsapp when you can use the free made in Sheffield chat app Tengi and be in with the chance of winning up to £1,000 every week? During the super draw one winner gets an incredible £10,000, details above.
Tengi, which also gives away hundreds of weekly £25 and £5 prizes, is the ONLY chat app that does that. It’s unique.
Yes you can send texts, emoticons, photos, videos and audio messages. It tells users when their message has been delivered and read.
It’s easy to set up group chats with friends, family, work, clubs or organisations..
Tengi is free to download and free to use, by anyone with a mobile phone and a SIM card, with messages sent via the internet, including WiFi.
It also promises not to sell your data, give it to advertisers or use message content to help target adverts. There are no in-app purchases. No catches.
But here's the best bit. Pronounced ‘Ten-G’, with aims of raising the prize to £10,000 every week, or 10 ‘G’, has already given away over £100,000 in its first few weeks.
Lucky South Yorkshire folk Olesia Tartakovski, of Sheffield and Rotherham’s Mark Carew, of Herringthorpe, already know what it’s like to win - they’ve each scooped the £1,000 weekly prize.
Here at Tech Talk we always feature an app of the week but after trying out Tengi myself for the past few weeks well, I’ve already got this in the running as app of the year. And it’s only February.
