Yakult's Brainteasers

Yakult celebrated its 80th anniversary by offering its customers a unique puzzle book: the Yakult Brainteasers.

Keesing created this entirely unique puzzle book full of puzzles with the Yakult theme incorporated in some way, either during the problem-solving or in the final solution.

Customers could receive the book by:

  • Making a request from the website;
  • Buying a promotional package of Yakult from the store; 
  • Solving an online wordsearch during which the customer was prompted to subscribe to the Yakult Netherlands newsletter. In addition to the booklet, customers had the chance to win a champagne breakfast.

The 30,000 books were individually sealed and Keesing ensured the delivery of all requested books, whether through the website or the puzzle & win promotion.

Facts & numbers:

  • The puzzle books were an enormous success. After 3 weeks, there was an additional print of 8,500 books;
  • Through the online wordsearch action, Keesing was able to activate 6,700 new subscribers to the Yakult newsletter;
  • The success with Yakult Netherlands lead to the same actions being offered at Yakult Belgium for both their Flemish-speaking and French-speaking customers.

What our clients say about Keesing

Paul McNamara

Tectonic mobile app United States of America

So addictive! The level 3 and 4 puzzles are too easy for me, but level 5 is perfect. Next time I'm going to try a level 6 or 7. It's been great to move up the levels when I'm ready.

Julia Ripoll

Wordsearch mobile app France

These puzzles are a great pastime and moreover, a great workout for the brain!

Elizabeth Morgan

Sudoku mobile app United Kingdom

This app is great! I've been doing Sudoku's for a long time on paper, but I must say that the digital puzzles are much nicer. I especially like the sound effects. Thanks!
