8 Bit Tower Defense Unit Range: How to See It and What the Circle Means
How to see a unit's attack range in 8 Bit Tower Defense and what the placement circle tells you, plus range traits on unit cards and in-match range values, upgrades that can enlarge coverage, and the Show every range toggle in Settings.
Range in 8 Bit Tower Defense is shown directly on the battlefield. Whenever you place a unit during a match, the game draws a circle around its spot, and everything inside that circle is what the unit can attack from there. This page covers where you see that circle, what it tells you before you commit to a spot, how range shows up on unit cards and in-match values, and where the dedicated range setting lives.
Quick answer
You see a unit's attack range as a circle on the map during placement: tap a lit spot beside the road in a match, and the circle around it previews everything that unit can attack from that position.
- Placement targets are lit tiles that sit inside each unit's attack circle, so the highlighted spots are ones the unit can actually cover.
- Unit cards and the in-match display also carry range info, such as trait text like Long range or a value like Range 10.
- Upgrading a unit during a match can enlarge its circle - after one upgrade a player noted the coverage was larger.
- Settings > GAMEPLAY includes a toggle named Show every range among the gameplay options.
The placement circle: what it shows
The in-game tutorial spells it out during your first match. Tip 3 of 6 reads: "Now tap the lit spot beside the road. Your unit attacks anything inside its circle." So the circle you see while placing is a live preview: pick a highlighted spot next to the road, and the area drawn around it is exactly the zone that unit will attack from that position. Enemies take damage while they are inside that circle as they travel the road.
That makes the circle a placement-decision tool, not just decoration. The tutorial's next step (TIP 4/6) has you place the Honey Bee and the Dart Dragonfly the same way, and in that placement flow the lit tiles sit inside each unit's attack circle - the game highlights spots that unit can actually cover. Because different units visibly differ from tiny to massive range, the same stretch of road can be a strong spot for one unit and nearly useless for another, which is exactly why range affects where a unit is worth placing.
Reading range before and during a match
The circle is the in-match view, but range information also lives on the unit cards in your Units inventory. The starter cards spell their roles out in trait text: Pebble Frog lists "Single target / Long range / Hits flying", Honey Bee lists "Swarm striker / Fast stings / Swarm bonus", and Dart Dragonfly lists "Dart volleys / Hits flying". Checking those traits before a match tells you whether a unit is built to reach far from its spot or to fight up close where enemies bunch up.
In a match, the display also shows concrete values. One player looking at a newly summoned unit reads "Range 10" straight off its screen, reacts to the massive coverage, and places it where the circle spans a huge portion of the road loop; later, looking at a different unit, they note it has tiny range and tuck it right against the road instead. Comparing these numbers and circle sizes between your units is how you decide which unit goes where.
Upgrades can enlarge the circle
Range is not fixed for the whole match. Tapping one of your units and pressing UPGRADE, paid with the cash that every defeat pays out, can enlarge its range circle. After spending match cash on one upgrade, the player looked at the unit's coverage and noted "Now it's larger." That was observed on one particular unit's upgrade rather than as a stated universal rule, but it shows the circle is worth re-checking after you invest in a unit: a spot that barely reached the road before may cover much more of it afterward.
The "Show every range" setting
Range display is also a settings topic. In Settings > GAMEPLAY, the menu lists a toggle named "Show every range" alongside the other gameplay options: Auto-skip waves, Auto-abilities, Skip summon animations, Ask before selling, Ask before traits, and Ask before trait rerolls. If you are looking for a setting that controls range visibility, that toggle is the dedicated entry in the GAMEPLAY tab.
Where range fits in your wider setup
The circle answers one question at a time - what this unit covers from this spot - but it connects to the rest of the game. Placement decisions build on the basics in the how to play guide, and the spot-by-spot logic is covered further in how to place units. Since upgrades can widen a circle mid-match, the in-match upgrade path in unit upgrades is worth knowing too.
