Ludus’ 10th Anniversary

[摘要] It is not unusual for the Museu Nacional de História Natural e da Ciência (MUHNAC) to host open extensionevents on a Saturday. On 25 June 2016, however, the reason for the festivities was new: Associação Ludus (AL)1was celebrating its 10th anniversary!Along one of the avenues leading to Jardim Botânico,several tables were prepared for games. Besides the Rubik’s cube and origami, one could find traditional games,such as Mahjong, but the boards were mainly intendedfor abstract (i.e. mathematical) games. Visitors could playHex, Amazons, Dots & Boxes, Traffic Lights, etc. These,among others, can be found at the National Championship of Mathematical Games,2 a competition that hasbeen attracting over 100,000 young people each yearsince 2004. In these games, luck plays no part. To beat theopponent, a player must be better at thinking with rigourand creativity.
