Nintendo of Europe has delayed the Dr Kawashima's Devilish Brain Training release date "to optimise the best possible launch timing of this title".
The first 3DS entry in the Brain Training franchise, Dr Kawashima's Devilish Brain Training had been due for release this Friday.
The platform holder said in a statement issued to Nintendo Life: "Nintendo has made the decision to push back the launch date of Dr Kawashima's Devilish Brain Training: Can You Stay Focused? for Nintendo 3DS to optimise the best possible launch timing of this title within the European market.
"We apologise for any inconvenience this may cause and we hope to announce a new launch date soon."
Featuring concentration and working memory exercises, the third game in the series hit Japan in July last year and received a delayed US release earlier in 2013.
