daily

func Mode ¶

func Mode(date time.Time) (game.SeededSpawner, string, string)

Mode selects the daily mode from the eligible pool using rendezvous hashing (highest random weight). Each entry is scored by hashing the date together with its (GameType, Mode) pair; the highest score wins.

This is resilient to changes in the pool: adding or removing an entry only affects dates where the changed entry would have been the winner.

func Name ¶

func Name(date time.Time) string

Name generates the daily puzzle name in the format: "Daily Feb 14 26 - amber-falcon"

Name uses its own sub-RNG derived from the date so that changes to the namegen word lists cannot affect mode selection or puzzle generation.

func RNG ¶

func RNG(date time.Time) *rand.Rand

RNG creates a deterministic RNG seeded from the given date.

func Seed ¶

func Seed(date time.Time) uint64

Seed returns a deterministic uint64 seed derived from the date.
