Digit Rush

What is Digit Rush?

Digit Rush is a neon arcade game built around a single glowing orb carrying a number. The rule set is deliberately tiny: anything smaller than that number is food, anything larger is a threat. Green marks the edible orbs, red marks the ones that will cost a life on contact, so the player spends every second reading a field of shifting sizes.

The arcade structure sits on top of that simple loop. There are one hundred levels in each of four modes, and the field grows meaner as the count climbs, with larger and faster enemies shrinking the safe windows between touches.

It runs as an HTML5 title and is free to play. Progress is stored in the browser, so an unfinished climb does not vanish when the tab closes.

How to play

Every run starts with a numbered orb under the player's control. Green orbs carry smaller numbers, which means they can be swallowed, and each one eaten makes the orb grow. Red orbs carry larger numbers, and brushing one costs a life. That comparison is the whole game, repeated faster as levels advance, because enemies arrive larger and quicker and the calm gaps between them get shorter.

Four modes reshape the stakes. Instant death ends the run on the first touch. Room for error hands over three lives. Take it slow also grants three lives but halves enemy speed, which makes it the gentlest entry point. With pause copies Take it slow and adds gifts that can be triggered from the pause menu.

Reaching a level once unlocks it as a future starting point, so a wall does not have to be cleared twice. Progress is kept in the browser between sessions.

Controls

The orb follows the mouse cursor on desktop and a finger on touchscreens, so steering is a matter of leading the orb rather than tapping directions. Phones play in landscape, which keeps enough of the field visible to judge sizes before committing to a move.

Space freezes every orb on the field while the player's own orb keeps moving, a clean way to cross a crowded screen. That freeze is unavailable in Instant death, where the run ends on a single touch.

Enter or Esc opens the pause menu. Three letter keys handle stored gifts: Q for shield, W for magnet, E for push. Pause-menu gifts become available every two minutes of play, and which ones appear depends on the mode.

Everything runs in the browser with progress saved locally, so a session can be resumed later rather than restarted from the first level.

Tips for your first run

Start in Take it slow. Three lives and half-speed enemies give room to learn how quickly the field turns hostile, and the habit of scanning numbers before moving is easier to build without a one-touch death waiting. Once the reading becomes automatic, Room for error and Instant death test whether it holds.

The pause menu is a resource, not a time-out. Gifts appear there every two minutes of play in the modes that offer them, so on a long run it is worth opening the menu rather than hoarding abilities that never get used.

Treat Space as an escape hatch rather than a habit in the modes where it works, and keep the shield, magnet and push keys in mind for the moments when the screen fills with red.

• Learn in Take it slow before moving to Instant death
• Scan every orb's number before crossing open space
• Spend pause-menu gifts instead of saving them
• Freeze the field with Space to escape a closing pocket
• Use Q, W and E for shield, magnet and push
• Reach a new level once to unlock it as a starting point

Content and replayability

The headline number is four hundred levels, split evenly across the four modes, and each mode plays by its own survival rules rather than a cosmetic reskin. Reaching level one hundred in a mode earns a card, which gives a long-term target beyond the next screen.

Rare emoji drop during runs and fill ten themed sets, among them Gourmet, Cosmos, The Deep, Arena and Rhythm. Collecting across sets rather than chasing one gives repeat runs a second reason to exist, since a drop can arrive at any point in a climb.

Gifts add variety inside a run: slowdown, a magnet that pulls green orbs in, a push that shoves red orbs away, an extra life, a shield, and a freeze that stops every orb while the player keeps moving. Life, shield, magnet and freeze can also be taken from the pause menu every two minutes of play, with the available options depending on the mode.

Level unlocks mean practice is permanent. A run that dies at level sixty still leaves a new entry point for the next attempt, which softens the sting of Instant death.

Presentation and performance

The look is 2D neon, built around glowing circles against a dark field. Because the read of the screen matters more than the spectacle, the visual language stays legible: colour tells the player which orbs are food and which are fatal, and the number on each orb confirms it.

The soundtrack was generated with AI, and the sound effects are synthesized in code inside the browser rather than streamed, which keeps the load light. Text is set in the Exo 2 typeface under an open font licence.

Digit Rush is version 1.0.3 and the first build released on itch. It is playable in English, Russian and Spanish, and it is built to run on desktop and on phones held in landscape without an install step.

The game was made by ais235 with AI assistance across the build: coding assistants helped write the code, an image generator produced the character and menu art, and the music came from a generative tool.

Who should play it

Digit Rush suits players who like a rule they can hold in one hand and a difficulty curve that does the rest. The eat-or-avoid decision takes seconds to learn, and the climb through one hundred levels per mode is where the pressure comes from rather than from a growing list of mechanics.

It is a good fit for short browser sessions on a laptop or a phone in landscape, particularly for anyone who wants a high-score chase without an account or a download. The four modes let the same player switch between a forgiving three-life run and a single-touch Instant death attempt depending on mood.

Collectors get a parallel track: ten themed emoji sets and a card for reaching level one hundred in each mode. Players who bounce off twitch arcade games may find the later levels punishing, since enemies keep getting larger and faster, but Take it slow exists precisely for that audience. The free price and the browser format mean trying it costs nothing but a click.
