WikiTest is a modern book test that uses a borrowed smartphone.

- You ask a spectator to search for ANY object or person on Wikipedia on THEIR phone to bring up its article.
- Whilst you look away, the spectator scrolls through the article and thinks of a random word on the page.
- You then tell the spectator EXACTLY what object they're looking at, as well as what word they're merely thinking of on the page!

The text (and of course their phone) can be thoroughly inspected after the routine with NOTHING to find!

* Works with ANY borrowed modern smartphone, tablet or computer.
* You NEVER touch their phone!
* VERY easy to perform.
* NO accomplice required.
* NO memory work needed.
* Works in English, French, German, Spanish, Dutch, Italian, Swedish, Brazilian Portuguese, Norwegian, Danish and Japanese, with more languages added regularly.

Simply phenomenal!!!

WikiTest is the best mentalist effect I’ve ever come across. I think that it’s so good that I got an IPhone as my next phone specifically so that I could get to have WikiTest on it. Something I really like about WikiTest is the fact you’re always prepared with something memorable for if, when or once someone asks to see something so to speak during casual situations or after the end of a gig when you don’t necessarily have any formal props on you.

WikiTest is worth every single penny I feel. Something which I also liked is the fact that Marc seemed genuinely really friendly when I initially emailed him with lots of enquiries before getting the app. I thought that WikiTest was too good to be true but it turns out that it is the real deal. I’m so glad the boys from the magic shop recommended WikiTest to me. Thank you Marc!

Devastatingly incredible

I've been using Wikitest for several months now, and it absolutely destroys!

Within a short period of time of going through the instructions and stuff I was confident to go and use it In my professional repertoire.

In my opinion this is worth so much more than the price listed as of November 2017! I simply cannot put into words how good this effect, idea, routine is.

It's modern and everyone can relate, everyone uses or knows if Wikipedia which makes it such a worker. Not only that but the features and settings on offer can make the imagination run wild.

Marc updates constantly and also responds promptly to any questions users have regarding Wikitest.

I can't thank or praise this genius enough for coming up with this and releasing it, this absolute gem!

This app is simply incredible. Every aspect of the performance has been thought through and the creator keeps the app up to date with new features and improvements. The customer service is second to none, with any support requests being quickly dealt with by email or on the Facebook group. Highly recommended.
