The word "cross-ens" means "cross-section of the meaning" and this method is developed by writer, teacher, mathematician and doctor of technical sciences, artist and philosopher. The cross-ens method was first published in 2002 . It is a standard field of nine squares in which the images are placed.

Your task is to explain the cross-line, to make a story - an associative chain, by means of the interrelation of images.

Nine images are arranged so that each picture connects with the previous and next, and the central combines several contents.

​Connections can be both surface and deep, but in any case, it is an excellent exercise for developing logical and creative thinking.

Crossens is an associative puzzle of the new generation that combines all the best qualities of many famous intellectual entertainments. Participants should recall an associated chain between pictures and understand the main idea that unites all pictures together.

Read the cross-ens need to top-down and left to right, continue to move only forward and end on the central 5 square, thus turns the chain wrapped like "snail".
