  "markdown": "Every spark system in the genre descends from what happened in Granblue Fantasy across ten weeks in early 2016. This page documents the incident and the fix, both unusually well sourced for gacha history because the fallout reached the financial press.\n\n## The incident\n\nDuring the year-end Legend Festival running into January 2016, Cygames featured Anchira, a Year-of-the-Monkey zodiac character, at boosted rates with a tightening availability window. Players chased her at extraordinary cost. The case that defined the story: a streamer documented spending about 686,000 yen (about US$6,065 at the time) on 2,276 draws in roughly one night before obtaining her. [[1]](#ref-1) More than two thousand players signed a protest petition, complaints reached Japan's Consumer Affairs Agency, national television covered it, and Bloomberg reported that the episode helped wipe over US$1 billion off Japanese mobile game company shares. Western coverage called it \"Monkeygate\". [[1]](#ref-1)\n\nThe structural problem was the one [Fate/Grand Order](/fate-grand-order) players knew well: a fractional rate-up with no floor. Nothing prevented a 2,276-draw dry streak on the featured character, and nothing guaranteed draw 2,277 either.\n\n## The response\n\nCygames apologized in early January 2016 and granted compensation in crystals matching festival spending. The durable changes shipped on March 10, 2016, the game's second anniversary: [[2]](#ref-2)\n\n1. Per-item drop rates became public for premium draws, listing every weapon and summon with its exact probability, ahead of any legal requirement.\n2. Every premium draw began granting one cerulean spark. 300 sparks (90,000 Crystals, roughly 90,000 yen if fully paid) exchange for any item on the promotion's list, including the rate-up characters. Sparks expire when the promotion ends.\n\nSix weeks later, on April 27, 2016, Japan's industry body CESA adopted guidelines requiring member companies to disclose gacha rates or spending estimates, with the major publishers as endorsers. [[3]](#ref-3) Voluntary crisis response became industry norm; the norm later became law elsewhere (see [rate disclosure](/wiki/rate-disclosure)).\n\n## The legacy\n\n\"To spark\" a character now means banking 300 pulls in any game, and the Japanese term tenjou (ceiling) covers the whole family: Blue Archive's and Umamusume's 200-point exchanges, Arknights' 300 [Data Contracts](/arknights/wiki/headhunting-data-contracts), NIKKE's persistent mileage, and FGO's 330-roll guarantee are all descendants. The full family tree is on the [spark](/wiki/spark) page, with current values in the [comparison table](/compare/pity-systems).",
