How to Play
Your teal block sits at a fixed height near the bottom of the play area and can only move left and right — there is no jumping, no shooting, and nothing to collect. Red blocks fall from the top of the screen, and touching any one of them ends the run instantly. Your score counts up automatically at ten points per second of survival, so a score of 300 means you stayed alive for thirty seconds. Press Space or tap the screen after a crash to start a new run.
On a keyboard, the Left and Right arrow keys move you at one fixed speed for as long as you hold them. There is no acceleration and no sliding — you start and stop the moment you press and release, which makes small corrections completely predictable. On a touch screen, press anywhere on the play area and your block travels toward your finger's horizontal position at that same capped speed. It homes in rather than teleporting, and lifting your finger leaves the block exactly where it was. Because the block chases an absolute position rather than a swipe direction, you can park your finger ahead of the block and let it come to you.
Why Watching Your Own Block Makes You Late
The most common mistake in a falling-obstacle game is keeping your eyes on the thing you control. It feels natural — your block is what you are steering — but the bottom of the screen is where information arrives last. By the time a block is close enough to look dangerous down there, most of your reaction window has already been spent watching it fall.
Every block enters at the top edge and travels the full height of the play area before it can reach you. That descent is your entire planning budget, and it is only generous early on. A block spawning in the first few seconds falls at somewhere between 120 and 220 pixels per second and takes several seconds to arrive. The same block spawning at score 300 falls at 420 to 520 pixels per second and reaches you in a little over a second. If you only start processing a block halfway down, you have thrown away half of a window that is already shrinking.
The practical fix is to rest your gaze near the upper third of the play area and treat your own block as peripheral information. You do not need to look at something you are already touching — your hand knows where it is. Players who make this switch usually report that the game feels slower, even though nothing about it changed.
Center or Edge: Where to Wait
When nothing is immediately threatening you, you have to park somewhere, and the choice matters more than it looks. The play area is 480 pixels wide and your block moves at 320 pixels per second, so crossing from the middle to either wall takes roughly seven tenths of a second. Crossing the full width takes about one and a half seconds.
Waiting in the center splits that cost in half in both directions. Waiting against a wall makes one direction free and the other expensive, and worse, it removes an option entirely — a block landing on the wall you are hugging leaves you only one escape route, and if a second block is covering that route you are finished before you start moving. The edges are only worth using as a temporary answer to a specific block, not as a resting position.
There is one refinement worth knowing. Falling blocks vary in size from 24 to 56 pixels wide, and the collision check combines their width with yours. A large block effectively threatens a corridor about 96 pixels wide, while the smallest ones threaten only about 64. That means the play area is roughly five large-block corridors across, and the gap you need to survive is smaller than most players instinctively leave themselves. You can slip past much closer than feels comfortable.
What Actually Changes as Your Score Climbs
Two things scale with your score, and they scale differently. Blocks spawn every 0.6 seconds at the start, and that interval shortens steadily until it bottoms out at 0.15 seconds — a floor you reach at around score 225, roughly twenty-two seconds in. After that point the game is not adding blocks any faster; the screen density has already reached its maximum.
Fall speed, however, keeps climbing with no ceiling at all. Each new block's speed is a random base plus your current score, which means late runs are not about more blocks but about less time per block. Somewhere around score 100, the fastest falling blocks are already covering ground vertically faster than you can move horizontally. From there on, being in the right place matters more than reacting quickly, because reacting quickly stops being enough.
This is why the game rewards early positioning discipline that feels unnecessary at the time. The habits you build in the first twenty seconds — staying central, reading the top of the screen, making small corrections — are the only things that still work at the speeds you meet after a minute.
Simplifying Your Decisions Under Pressure
Once six or seven blocks are on screen, trying to track all of them is counterproductive. The useful mental model is to reduce the screen to a single question: which blocks can reach my row before I can move out of their corridor? Anything that will land well to your left or right is not a threat and does not deserve attention, no matter how visually busy it is.
- Track the two or three lowest blocks that are roughly above you. Everything higher is a problem for a later second, and everything far to the side is not a problem at all.
- Prefer the shorter dodge. Two small side-steps in the same direction are safer than one long commitment, because each step lets you re-read the screen before spending more room.
- Move into space, not away from danger. Fleeing a block often walks you under the next one; picking the widest visible gap and heading there solves both problems at once.
- When two blocks bracket you, go early. Waiting to see which one is "really" coming costs you the room to answer either.
Touch and Keyboard Are Not the Same Game
Both control schemes are capped at the same movement speed, so neither is faster in raw terms, but they fail in different ways. Keyboard input is binary — you are moving at full speed or not at all — which makes precise, short adjustments easy and long repositioning a matter of holding a key and waiting. The risk is overshooting, because releasing a moment late costs real distance.
Touch input is positional. Your block seeks the exact horizontal point under your finger, so it stops on arrival by itself and cannot overshoot. The trade-off is that your finger and hand cover part of the screen, and the block only moves while you are pressing. The most effective touch habit is to keep contact more or less continuously and slide, rather than tapping at destinations, and to keep your hand low so it does not obscure the top of the play area where the blocks you actually need to see are entering.
About Dodge Blocks
Dodge Blocks is a free browser survival game with a single mechanic and no downloads, accounts, or loading screens. You control one square, you move on one axis, and the only measure of success is how many seconds you last against an obstacle field that gets steadily faster. The whole game is visible on one screen, which makes it unusually honest — every death is something you could have seen coming.
Because difficulty is tied directly to your score rather than to fixed levels, the game tunes itself to whoever is playing. A first run ends in gentle traffic; a practiced run ends in a wall of blocks moving several times faster, and both take the same simple inputs. Your personal best is stored locally in your browser, and a share button appears after each run so you can pass your score along and see whether anyone can beat it.
