Why Typing Stack is different from a normal falling-letter game
Most falling-letter games simply remove a target when it reaches the bottom. Typing Stack turns every miss into a lasting consequence. A letter or word that reaches the floor becomes a solid block. The next missed item can land on top of it, then another block can stack above that. A few isolated mistakes are manageable, but repeated misses begin to remove open space from the canvas and create visible pressure. This makes accuracy matter just as much as raw reaction speed.
The game is designed as a survival competition rather than a short fixed round. Every run begins at Level 1 so scores are comparable. The early stage is deliberately forgiving, giving you time to understand the mechanic and establish a rhythm. Automatic level changes gradually increase fall speed, target frequency, and simultaneous pressure. Level durations grow from one minute at Level 1 to ten minutes at Level 10. The final expert stage adds a 70 WPM mastery gate, so strong typists have a meaningful long-form target rather than an easy endless loop.
Letters, words, and mixed practice
Words is the default mode because it produces a more natural typing rhythm and the existing word timing is already well balanced. Letters is the reaction mode and now begins at a controlled pace before becoming progressively faster; the former Level 1 speed does not arrive until Level 5. Later levels can introduce occasional capital letters, so advanced play also rewards quick Shift control. Words uses an expanded library of more than 800 unique course and everyday words, shuffled in large level-based bags so immediate repetition is rare. The blocks progress from shorter to progressively longer words. Start typing a visible word to lock onto it; the completed word disappears before landing. Letters + Words combines both target types, forcing you to switch between instant single-key reactions and short word sequences.
There is intentionally no on-screen keyboard inside the game. The canvas is the competition area. This keeps the learner looking at the falling targets instead of looking down at a virtual keyboard, and it gives the game more visual space on desktop screens. A Full Screen button is also provided for players who want the widest possible competitive view; the HUD, level progress, controls, and final result remain available in full-screen play.
Scoring and improvement
Correct typing now gives a soft positive sound, with a slightly brighter chime when a full word is cleared; these effects respect the site sound setting. The scoring is intentionally simple and transparent: every correct character typed equals 1 point. A one-letter target is worth 1 point, while a five-letter word can add 5 points as you type it correctly. Streak and level are still tracked as separate achievements rather than hidden score multipliers. Wrong keys break the streak and reduce accuracy, while untyped targets become dead blocks that permanently increase the stack. The result screen records score, level reached, survival time, WPM, accuracy, cleared targets, and dead blocks.

Frequently asked questions
Can I remove a block after it has landed?
No. A landed target is intentionally treated as a dead block for the rest of that run. The only way to keep the board clear is to type targets before they land.
Does every run start at Level 1?
Yes. This keeps the competition fair and ensures that the difficulty grows naturally during the run.
How long can a full challenge last?
The ten scheduled levels total 55 minutes: 1 minute for Level 1, 2 minutes for Level 2, and so on through a 10-minute Level 10. A run can still end earlier if the stack reaches the danger line. Level 10 can continue into Expert Overtime until the rolling one-minute speed reaches 70 WPM.
