Summary The ESP Lite system is a quasi ESP game that mimics the ESP game [1], but differs in two respects: 1) once an agreement is reached, the agreed word becomes a taboo word (i.e., the threshold for defining a taboo word is set to one in ESP Lite); and 2) it embeds the three playing strategies proposed in [2] transparently and records the complete game trace for evaluation and further research.

The ESP Lite system was released on March 9, 2009. Within one month (by April 9), it created 3,130 games, played 9,376 distinct puzzles, and reached 12,312 agreements. The OPSA scheme was used in 1,444 of the games, which played 575 distinct puzzles and reached 3,418 agreements; the RPSA scheme was used in 812 games, which played 4,380 distinct puzzles and reached 4,473 agreements; and the FPSA scheme was used in 874 games, which played 4,421 distinct puzzles and reached 4,421 agreements. The players were from 606 distinct IP addresses (588 in the Taiwan, 12 in USA, 2 in Hong Kong, and 4 in various other countries). Most of the players in Taiwan were students.
