Reverse The Odds

By Channel 4

Open iTunes to buy and download apps.


Reverse The Odds is a fun and unique puzzle adventure game where the further you progress the more you are helping to beat cancer sooner. And it's all free!

Play at your own pace, whether you just have a few minutes waiting for the bus, or hours to kill on the train, you can build a wonderful Odd world and help save lives by improving cancer treatments sooner.

- Over 350 levels.
- Meet the Odds. A collection of unique colourful little characters who need your help to return their world to life.
- Revitalise a desolate wasteland into an amazing wonderland.
- Easy to learn with increasing challenge and difficulty.
- Directly help Cancer Research UK scientists to beat cancer sooner.
- Combine your efforts with a worldwide community of players.

By examining the patterns within cancer cell slides and identifying aspects such as the number of cells or the colour of cells, you can move up game levels and achieve rewards… Don’t worry about getting your analysis wrong – the same cell slide data will be studied by many other users to ensure accuracy and no single person’s diagnosis or treatment is affected by your actions - your analysis underpins research for future treatments.

Customer Reviews

No guilt!

One of few games which you don't need to feel guilty for being addicted to! It's such a worthy cause, and it's great that anyone can be a part of it.

As a game, my only annoyance is at the timer function on the potions - I understand that it creates interest, but it's also beginning to ruin my enjoyment of it. The 'matching' system is taking a long time to give me results, so even if I have matched correctly, I still have to wait.

Nonetheless, a great, addictive game for an amazing cause and charity.

Cancer support

It's great in all ways e.g health and it's soooooo fun! It doesn't just come in all seriousness it also comes with fun games so I recommend reverse the odds to everyone! HELP BEAT CANCER!! also I forgot to mention that there are NO payments and u don't have to pay to have the app like other apps so I recommend you get it!!🙏

Without A Doubt

This is without a doubt one of the greatest, most awareness raising games I have ever come across! And the best thing is it's all for a good cause 🙂 hands down one of the best things ever! Now even children can STAND UP TO CANCER!
