TubeSort
Guide
This page explains how to play TubeSort.
How a level works
- Tap a tube, then tap another tube to pour.
- Only the color at the top moves, and only into an empty tube or onto the same color.
- Each level starts with exactly two empty tubes.
- There are 1,000 levels. Every level is prepared in advance, so the same level is the same for every player. Levels 5, 10, and then every 25th level are a step harder. Every level can be solved.
The path
Beside the level on the home screen there is a path. The road curves through the levels. It can be followed back to level 1, and forward only through the next 25 levels. The circle for the current level starts that level.
Coins
Pouring a color onto the same color adds one coin for each segment that moves. The shared list ranks players by level, then by coins.
Helpers
An extra empty tube costs 500 coins and is available from level 1. Undo costs 400 coins and is available from level 5.
Color marks
Color marks are optional in Settings, for players who find colors hard to tell apart. They are symbols on the liquid, not a separate mode.
Shop
Backgrounds cost 500 coins or €0.99. Tube designs other than Classic cost 500 coins or €0.99. Classic is free. An empty tube costs 500 coins. Undo costs 400 coins and opens at level 5. Coin packs are 600 coins for €0.99, 1400 for €1.99, 2500 for €2.99, 4500 for €4.99, and 7000 for €6.99. Coin packs are consumable. After Apple delivers them, they are not returned. The coins stay in the progress on the phone.
Remove ADS
Remove ADS costs €4.99. It stops the ads between levels and adds 1000 coins once. When the app opens again, the purchase is recognized and the coins are not added a second time. There is no Restore Purchases button. Ads in the shop remain.
Ads
The game uses Google's test ad units. Real AdMob ads are not connected yet.
The ad between levels starts at level 4 and then appears every third level. It disappears after Remove ADS. Optional ads in the shop remain: 50 coins at most 3 times a day, an empty tube every 6 hours, and undo every 4 hours. The reward is given only after the ad finishes.
A rewarded ad gives 50 coins, at most 3 times a day. An empty tube from an ad is available every 6 hours. Undo from an ad is available every 4 hours. The reward is added only after the ad is watched to the end. Turning the clock back does not renew these limits.
TubeSort asks for Google consent through Google Mobile Ads. If that form does not appear, the game does not treat the absence as a yes. On iPhone, Apple then asks whether the app may track. The game still runs if you refuse. Google and its advertising partners may use a device identifier to measure ads.
Offline
A level can be played with no connection. The shared list updates when the phone is online and signed in with Apple.
The game runs offline. Progress stays on the phone. The shared leaderboard updates when there is an internet connection and an Apple account. Sign in with Apple is used for that list.
The list shows the Game Center name, or the nickname if the player chose one. The Apple account name is kept and is not shown. A nickname has 5 to 15 characters, no spaces, and it is unique.
If a purchase or an account needs a closer look, use Support.
