Srimad Bhagavatam Canto 10, Chapter 14, Text 61

SB 10.14.61

evam viharaih kaumaraih
kaumaram jahatur vraje
nilayanaih setu-bandhair
markatotplavanadibhih
 
Translation: 
 
In this way the boys spent their childhood in the land of Vrndavana playing hide-and-go-seek, building play bridges, jumping about like monkeys and engaging in many other such games.
 
Purport: 
 
According to Srila Sanatana Gosvami, the word nilayanaih refers to games such as hide-and-go-seek or cops and robbers. Sometimes the boys would jump around like the monkeys in Lord Ramacandra’s army and then enact the building of the bridge to Sri Lanka by constructing play bridges in lakes or ponds. Sometimes the boys would imitate the pastime of churning the Ocean of Milk, and sometimes they would play catch with balls. We can find full pleasure in the spiritual world, with the simple condition that everything be performed in pure love of Godhead, Krsna consciousness.
 
Thus end the purports of the humble servants of His Divine Grace A.C. Bhaktivedanta Swami Prabhupada to the Tenth Canto, Fourteenth Chapter, of the Srimad-Bhagavatam, entitled “Brahma’s Prayers to Lord Krsna.”
