Train of Thought Instructions

The goal of Train of Thought is to correctly guide each train to their matching station by changing the switches on the track by clicking (or tapping) the circled part of the track .

You need to plan ahead as much as possible by switching the tracks before the trains arrive at the pivot point. This ensures that the trains follow the path to the correct stations.

If you click (or tap) too many times too quickly, then the tracks may not stay in the direction you intended.


There is a green train coming but the current tracks aren't configured in a way to get it home. To get it to the correct station, you need to click (or tap) on the switch where the arrow is pointing:


After clicking (or tapping) the switch, it changes the direction the green train goes and leads it back to the correct station. 

Now you see that a pink train is coming down the tracks. You need to click (or tap) the same switch again to direct the pink train to the correct station.

Scoring & Leveling

Your score is dependent on the level you play on as well as the number of correctly directed trains. Each train is worth 100 points. Points are multiplied by the current level to determine the final score at the end of each session. You don’t lose points for directing a train to the wrong station.

In the early levels of Train of Thought, you can miss up to 3 trains but still move up to the next difficulty level. For Levels 11 and 12 of Train of Thought you can only miss 2 trains. At Level 13 you can only miss one.

The game adjusts how fast trains are released based on how many mistakes you make. The game sends the trains out more slowly once you make a mistake. Make fewer mistakes to increase the speed at which the trains are released. You could be getting different amounts of trains within the same level depending on how many mistakes you make. Please note, this doesn’t change the fact that you may only make a certain number of mistakes to move on to the next level.

There are 14 distinct levels. When you reach Level 14, if you complete the round and make only 1 mistake, you move up a sublevel (i.e. the next time you play, you're still on Level 14, but there are more total trains possible to be given). There are several different sublevels within Level 14 and a maximum total of 90 trains.​ In Level 14, the number of trains you’re given each game adjusts based on your performance. While you may have unlocked more trains after one game, if you made 4 or more mistakes, then the next time you play the game adjusts to include fewer trains. If you complete that round without a single error you unlock more trains for the next game.
