Changelog

1.9 — Expeditions, core research and today’s requests

2026-11-04

• New expeditions: once you reach Fluorite, send one out from the top of the Mine tab. It comes back with crystals after two hours; collect them and it sets out again
• New core research: spend research points to grow a little stronger. What you learn stays through every rebirth. Points come from new seams, rebirths, expeditions, today’s requests and the daily gift
• New today’s requests: three small goals each day. Finish all three for a research point
• The daily gift now includes research points on days 3 and 7
• Tabs now show a small mark when something there is ready
• The iPhone app gets the same changes in version 1.4. In the app you can also double the crystals an expedition brings back with a short video, which is always optional, and get a silent reminder when an expedition is back if you allow it

1.8 — A daily gift, and earnings while away

2026-10-20

• New daily gift: open the game once a day and a gift is waiting, with a bigger one on day 7. Missing a day never sends you back to the start; you carry on where you left off. The seven-day calendar is always in the Bonus tab
• Coming back to a tab or app you never closed now counts the crystals that built up while you were away. Before, they were only counted when the game was opened afresh
• Fixed: catching an orb (Echo) while your income was doubled no longer cuts the doubling short
• The iPhone app gets the same changes in version 1.3. In the app you can also double the away crystals and the daily gift with a short video, which is always optional

1.7 — Very large numbers, written short

2026-10-08

• From one trillion up, numbers are now written short, like 1.23 × 10⁴¹. A player with a 42-digit crystal count told me the number filled several lines and pushed the buttons out of easy reach. Thank you
• The crystal count at the top now always fits on one line, even at the largest text size
• Cores and the multiplier are shortened the same way, with the decimal mark of your language (1,23 in French, for example)
• The iPhone app gets the same fix in version 1.2

1.6 — States that read without colour, and less motion

2026-10-02

• In the Mine tab, the chosen amount (×1, ×10, ×MAX) is now marked in bold with a thick underline, not by colour alone. It reads the same on a greyscale screen
• With Reduce Motion turned on, the bonus orb now crosses in a straight line instead of bobbing, and the crystal swells less when tapped
• Turning that setting on or off now takes effect at once, without reopening the game
• From five languages to seventeen. Added Traditional Chinese, French, German, Italian, Portuguese, Dutch, Polish, Russian, Turkish, Vietnamese, Thai and Indonesian
• No language switch any more: the game appears in the language of your device (or browser). A language it does not have is shown in English
• Shared progress now ends with a link to this site, which social networks show as a card with a picture
• iPhone app (1.1): web fonts are no longer requested inside the app. Launching it makes no network request other than for adverts
• iPhone app (1.1): players in the EEA, the UK and Switzerland now have a Privacy settings button for changing their ad consent later. It does not appear elsewhere

The iPhone app is out

2026-09-30

• The same game is now on the App Store (free, iPhone only)
• A code from Save data in the Menu carries your progress between the browser and the app

1.5 — Number abbreviations removed

2026-09-22

• K, M, B, 万 and 億 are gone. Numbers are shown at full length. Abbreviations are shorter, but each asks the reader to know a convention, and conventions differ by language. Digits mean the same thing to everyone
• Large on-screen figures now shrink as the digits accumulate
• Prices and per-second figures wrap instead of pushing the layout sideways. This was a layout problem the abbreviations had been hiding — past about twenty digits the screen overflowed
• Separators follow the language (1,234,567 in English and Japanese; 1.234.567 in Spanish)

1.4 — Positioning fixes

2026-09-22

• Announcements were appearing in the wrong place. On a wide screen they were centred on the window rather than the cave, which put them over the building list. They now sit at the top centre of the cave itself
• The depth read-out moved back to the bottom left so it no longer collides with the hint
• The home page no longer embeds the game; it links to it. Reading and playing are calmer apart

1.3 — Tap feedback pared back

2026-09-22

• The shockwave ring on tapping was removed
• The flash of light across the crystal was removed
• Feedback is now carried by the crystal swelling and the shards scattering. Fewer effects, each clearer, read better than more of them
• The site palette was rebuilt: dark text on a light ground by default, switching to a dark scheme when the device asks for one. Both were measured for contrast

1.2 — Tap feedback rebuilt

2026-09-22

• Tap particles raised from seven to between sixteen and thirty-two, at two to three times the size
• An expanding shockwave ring was added (removed again in 1.3)
• A flash across the crystal was added (removed again in 1.3)
• The crystal's swell was raised from 9% to 18% and now widens as well as lengthens, and lingers longer
• With the system set to reduce motion, the feedback had been disappearing entirely. In that mode the shards now appear already scattered and fade in place: the motion is restrained, the response survives
• A full-screen button was added at the top right (desktop and Android)

1.1 — Event and bonus tuning

2026-09-22

• Orbs now appear every ten minutes instead of every one to two. Rarer, so each is worth about twice as much
• An orb stays on screen for fifteen seconds instead of thirteen, and drifts more slowly
• Rewarded-video hooks added, off by default. Four of them: time skip, extended resonance, summon an orb, extra cores
• Bonuses moved to a tab of their own, capped at ten a day, resetting when the date changes
• The problem-report form moved to this site; the game keeps a link and a "copy the details" button

1.0 — Released

2026-09-22

The game

• Seams extended from seven to twelve. The five past Prism open one at a time, by rebirthing at the deepest seam you have
• Bulk buying added (×1 / ×10 / ×MAX)
• Every ten copies doubles a building's output, which gives the middle of the game something to aim at
• An opening guide for first-time players, cut down to three lines
• The depth ceiling was removed. Past the deepest seam it grows 4,000 m for every tenfold increase in the total

Looks

• Crystal dust now drifts through the cave air, coloured by the current seam
• The corners of the frame darken slightly, drawing the eye to the crystal
• A line of reflected light was added to the rock the crystal sits on

Legibility

• Four text sizes, scaling every piece of text on the page
• Five colour schemes, two of them maximum-contrast
• All pale text colours lifted to at least 4.5:1 contrast
• Affordable buildings no longer marked by colour alone — a "▸" and the border say it too
• Every button raised to at least 46 pixels tall
• The instructions given headings and separated item by item

Languages

• Five languages: English, 日本語, 简体中文, 한국어, Español
• Building names, seam names, event names, the full instructions and the share text are all translated
• Number units recalculated per language (万・億 / K・M・B / 만・억)
• Switchable in place from the globe at the top right

Saving and sharing

• The save code shrank from 312 characters to 47, using base 36 and a checksum. Old codes still load
• Sharing to X, Bluesky and LINE
• Earning continues at half speed while away, up to eight hours

Fixed

• Numbers were displaying incorrectly. "300 billion" showed as "3 billion" and "12 million" as "1.2 million", because the routine that strips trailing zeros after a decimal point was stripping them from whole numbers too
• A popup's HTML was malformed. A missing closing character stopped the seam and rebirth announcements from running. The apparently separate bug where the loop counter did not advance had the same cause
• The tap target was too generous. Tapping well away from the crystal still mined; it is now limited to the crystal itself
• Depth had been stuck at 28,000 metres
