Fig. 2.
Foldit players employ different recipes at different stages of gameplay. The relative frequency of usage for each recipe category is shown for three different stages of gameplay (blue, first third of gameplay; red, second third; green, final third) for all players (A) and for top ranked players (B). All players use local optimize recipes more frequently as gameplay progresses (A), and this trend is even stronger among top players (B). The usage frequency for each individual recipe is shown in detail in Fig. S2. The actual context dependence of the use of different recipes is likely greater than that shown in the figure; the division based on elapsed game time used here is relatively crude because different players in different puzzles may spend very different amounts of time on the opening, middle game, and end game.
