Changelog – Island Tycoon

Prestige exploit and Auto-Tapper fixes

21 August 2026

FIX Starting Capital could hand out so many coins in the late game that every district could be opened immediately after a prestige, allowing an instant repeat prestige. Starting coins are now capped at 10% of what opening the districts costs — the island always has to be earned. The change has no effect in the early game.
FIX The Auto-Tapper no longer plays the tap sound five times a second and no longer counts towards your tap total, so “tap N times” achievements no longer unlock on their own. Coin output and manual tapping are unchanged.

21 August 2026

NEW The game now lives at its own address, playislandtycoon.com. The old workers.dev address still works so saves stored there are not lost.
NEW Rewarded ads: watching an ad can double your offline earnings (up to 5×/day) or the coins from your daily bonus. Both are entirely optional — the base reward is always available without an ad. For now the ad slots play a placeholder.
NEW A privacy policy in Finnish and English, linked from the settings.
NEW These instructions and this changelog.
FIX Starting Capital is now capped. Late in a run, 10 minutes of income could be enough to buy one building in every district right after a prestige, letting you prestige again immediately without playing the island. Starting coins are now at most 10% of the cost of opening the whole island — the early-game boost is unchanged.
FIX The Auto-Tapper no longer machine-guns the tap sound. Automatic taps played the tap sound five times a second for as long as the game was open. Only your own taps make a sound now.
FIX The Auto-Tapper no longer unlocks tap achievements for you. Automatic taps counted towards your tap total, so "Tap 100 / 1,000 / 10,000 times" unlocked without playing. The counter and those achievements now track your own taps only — the Auto-Tapper's coin output is unchanged.

1 August 2026

NEW Prestige now unlocks only once every one of the six districts has at least one building. Previously the game could be reset partway through; now every run is a full playthrough.
FIX Large numbers displayed incorrectly at unit boundaries: 999.97 rounded to 1000 instead of 1.000K, and the same bug repeated at every unit for larger values.

24–25 July 2026

NEW Coin totals show three decimals instead of two, so small changes stay visible at large balances.
FIX Your score is now synced to the server before the leaderboard opens, so your rank is correct immediately.
FIX A grammar error in the daily bonus text.

23 July 2026

NEW Continue on another device by signing in with a Google account. If both devices have a save, the game shows the key figures for each and lets you choose which to keep — nothing is overwritten silently.

22 July 2026

NEW Buildings are now drawn with rendered sprites instead of the earlier emoji.
FIX The Gold Fever edge glow could stay on screen after the effect ended.
FIX The coin counter could briefly tick downwards during fast tapping.
FIX Text overflow and Finnish hyphenation on gem shop cards; Close buttons stand out better.
FIX The tap +value now rises more clearly above the point you tapped.

21 July 2026

NEW An idle game with 12 buildings, six districts, 21 achievements, five landmarks and a prestige loop.
NEW An island diorama that grows from a deserted island into a city as you buy: layered sea, sandy beach, vegetation and per-building animations.
NEW A public leaderboard (opt-in), with nickname moderation and deletion of your own data.
NEW English translation and a language setting.
NEW Offline earnings: the game credits time spent away when you return.
NEW Installable app (PWA) — the game can be added to a phone's home screen.
