PRACTISING WITH INTENT · LESSON 1 OF 4
Deliberate practice for Tetris
AFTER THIS GUIDEYou can turn a vague goal such as “stack better” into a short session with one observable behaviour.
Give the session one question.
“Get better at Tetris” is too broad to judge after ten minutes. “Notice when I cover the well” is specific enough to observe. Choose a behaviour you can point to on the board, then choose the mode that exposes it.
Start slowly enough to explain the decision. Gravity Off removes automatic descent and automatic locking in this trainer, so you can compare placements. It does not switch off timed garbage in Downstacking; pause that session when you need time to inspect.
Make a prediction before locking. Afterwards compare what happened with what you expected. Undo can help you test an alternative while the reason is fresh. Avoid simply replacing every move with the coach’s move without understanding the difference.
When the decision becomes repeatable, add a small timing demand. Try Slow gravity before Normal, or a shorter pause before each placement. Increase one demand at a time. If you stop seeing the target behaviour, slow down again rather than practising panic.
Turn “keep the well open” into a session
Set a small target
Choose 9–0, Gravity Off and NEXT 5. The question is whether each placement preserves a route down the right well. The well diagram gives you a concrete thing to inspect.
Play ten deliberate pieces
Before each drop, say where the next piece could land. If your move roofs over the well, note the piece number and compare one alternative with Undo.
Review one decision
At the end, select one placement you can now explain better. Repeat a short set with the same focus. Speed becomes the next variable only after the access check is reliable.
Open from the top: a usable well.

Common mistakes
Changing the goal after every awkward piece
That makes it difficult to tell what improved. Finish the short set, then decide whether the goal needs changing.
Measuring only lines or speed
Those numbers can improve while the target habit stays weak. Count the decisions you predicted correctly.
Using slow play forever without transfer
Once the skill is reliable, test a modest timing constraint. The purpose of slow practice is to make a decision you can later use faster.
TAKE IT TO THE BOARD
A ten-minute practice loop
- Spend one minute choosing a single board behaviour and a suitable mode.
- Spend six minutes on short manual sets. Predict, place, compare; use Undo for one meaningful alternative rather than every move.
- Spend two minutes reviewing a repeated mistake in Game history.
- Use the final minute to choose the next session’s focus from what actually happened.
What counts as progress? You end with a specific observation and a repeatable next task, not only a piece count.
Open practice ↗Opens the mode. Set Gravity and NEXT yourself; your current settings are kept.
