A League of Legends mouse does not need a wall of buttons. It needs the right two or three, in reach of your thumb. Most mouse lists skip that question, so this guide starts there: which in-game actions can live on a mouse, and which of five wireless mice can hold them?
We built a binding map from each mouse’s published button layout and League’s default controls, then picked on that map plus weight, battery and shape. GameVexo did not hands-on test these mice. Every spec comes from published information or the sources listed below.
The Logitech G PRO X SUPERLIGHT 2 is our best overall League of Legends mouse: Logitech lists it at 60 g with up to 95 hours of battery and five buttons, two of them under your thumb, enough for Flash and your trinket. Choose the Razer Viper V3 HyperSpeed for a fourth reachable button, or the Logitech G305 on a budget.
Our picks at a glance
Here are all five side by side. A “spare slot” is a button beyond left and right click that your thumb can reach mid-game. Weight, battery and button counts are the manufacturers’ published figures. Battery life is “up to”.
| Mouse | Weight | Buttons | Battery | Best For | Link |
|---|---|---|---|---|---|
| Logitech G PRO X SUPERLIGHT 2 Best Overall | 60 g | 5 (2 thumb) | Up to 95 h | One light mouse, two binds | Amazon → |
| Razer DeathAdder V3 Pro | 63 g | 5* (2 thumb) | Up to 90 h | Ergonomic, right-handed | Amazon → |
| Razer Viper V3 Pro | 54 g | 6 programmable (2 thumb) | Up to 95 h at 1,000 Hz | Lowest weight | Amazon → |

* Retail listings give the DeathAdder V3 Pro five buttons. Razer’s own comparison chart on Amazon lists six. We plan around five until that is settled.
How many buttons a LoL player needs
Two thumb buttons are enough. A third and fourth help, but in our view four spare slots is a comfortable ceiling for League.
League’s default controls keep the core actions on the keyboard, per the League of Legends Wiki: Q, W, E and R for abilities, D and F for summoner spells, number keys for items and the trinket, B for recall. In the default click-to-move scheme, right click moves and left click selects. An extra mouse button is a convenience that takes one action off a busy left hand, not a requirement.
It matters more under the WASD scheme added in patch 25.24. There, left click is the basic attack and Q moves to right click, per the wiki, so a spare thumb button is worth more.
| Mouse | Documented layout | Spare slots reachable mid-game |
|---|---|---|
| Logitech G PRO X SUPERLIGHT 2 | Left, right, wheel click, two left-side buttons (five) | 3: wheel click + 2 thumb |
| Razer DeathAdder V3 Pro | Same five-button layout, per retail listings | 3: wheel click + 2 thumb |
| Razer Viper V3 Pro | Left, right, wheel click, two thumb buttons; DPI switch on the underside, per reviewers | 3 (the underside DPI switch is hard to reach mid-game) |
| Razer Viper V3 HyperSpeed | Left, right, wheel click, two thumb buttons, center DPI button, per Tom’s Hardware | ⭐ 4: adds the DPI button |
| Logitech G305 LIGHTSPEED | Left, right, middle click, DPI button, two side buttons, per Logitech’s product copy | 3, plus the DPI button if it is within reach |
Smart cast and where to bind it
Smart cast is now called quick cast. It fires an ability at your cursor the moment you press the key, with no second click. Riot renamed it in patch 3.12, according to the wiki.
League has three casting modes: normal cast (press the key, then click a target), quick cast (fires at the cursor on key press) and quick cast with indicator (hold to see the range, release to fire). Quick cast is Shift plus the ability key by default, and you can set the mode per ability, summoner spell, item and trinket.
Quick cast changes what a mouse button can do. A thumb button bound to a quick-cast action fires in one press, at the cursor. Under normal cast, the same button only opens the targeting prompt, and you still click. So give mouse buttons to one-press actions. Flash is the easy first bind: the wiki lists it among the spells that always quick cast.
To get a mouse button into League, program it in the mouse software (Logitech G HUB or Razer Synapse), or bind it inside League. The wiki documents key codes such as Button 4 for the back side button, and advises testing changes in the Practice Tool first.
The binding map: League actions ranked by how well they suit a thumb button, using default keys from the League of Legends Wiki and the documented layouts above. The ranking is editorial judgment, not a test result.
| League action | Default key | Why it suits a mouse | 3-slot mice | 4-slot mice |
|---|---|---|---|---|
| Summoner spell (Flash) | D / F | Flash always quick casts, so one press fires it at the cursor | Thumb 1 | Thumb 1 |
| Trinket (ward) | 4 | Quick cast uses your cursor as the target | Thumb 2 | Thumb 2 |
| Alert ping | G, or Alt + left click | Pings land at the mouse position | Keyboard, or swap with trinket | DPI button |
| Camera drag | Middle mouse (wheel click) | Already a mouse action | Wheel click (default) | Wheel click (default) |
| Recall | B | No cursor needed | Keyboard | Keyboard |
| Item actives | 1, 2, 3, 5, 6, 7 | Fine on the keyboard. Move one to the mouse only if you press it constantly | Keyboard | Keyboard |
| Q, W, E, R | Q, W, E, R | Core abilities stay on your fingers. In the WASD scheme, Q sits on right click | Keyboard | Keyboard |
The three-slot and four-slot mice differ by one bind, a ping. Buttons alone should not decide this purchase. Weight, battery and shape matter more.
The five picks
Card images are original layout schematics, not product photos.
Logitech G PRO X SUPERLIGHT 2
60 g, up to 95 hours, and a five-button layout with two thumb buttons.
Logitech lists the Superlight 2 at 60 g, with a HERO 2 sensor up to 32,000 DPI and up to 95 hours of battery. It has five programmable buttons: left, right, wheel click and two on the left side.
That gives three spare slots: wheel click for the camera, one thumb button for Flash, one for your trinket. Those are the actions that gain most from a mouse, so we rate it best overall. The trade-offs are a right-handed design and no fourth slot. Retailers also list 4K and 8K versions, so check the Amazon page matches the model you want.
- Published weight of 60 g
- Up to 95 hours of battery life
- Five programmable buttons, two for the thumb
- Right-handed design
- Only three spare slots
Pick it for one dependable, light mouse and two binds. You give up a fourth slot.

Razer DeathAdder V3 Pro
63 g ergonomic right-handed shape with a five-button layout.
The DeathAdder V3 Pro is here for shape, not extra buttons. Razer lists it at 63 g with a Focus Pro 30K sensor, third-generation optical switches rated for 90 million clicks, and up to 90 hours of battery.
Retail listings show five programmable buttons, so the map matches the Superlight 2: three spare slots. The ergonomic right-handed shell is the difference. Razer’s own chart says six buttons, so treat the count as unsettled.
- 63 g published weight for an ergonomic shell
- Optical switches rated for 90 million clicks
- Up to 90 hours of battery
- Right-handed only
- Button count differs between sources
Choose it if shape is your first filter. Otherwise the Superlight 2 gives the same slots for less weight.

Razer Viper V3 Pro
54 g symmetrical shell with up to 95 hours at 1,000 Hz.
Razer lists the Viper V3 Pro at 54 g (55 g in white), the lightest of the five, with a Focus Pro 35K Gen-2 sensor, Gen-3 optical switches and polling up to 8,000 Hz. The catch, per Razer’s battery table: up to 95 hours at 1,000 Hz, but up to 17 hours at 8,000 Hz.
Razer lists six programmable buttons. Reviewers describe two thumb buttons and a DPI switch on the underside, so reachable slots match the Superlight 2. In our view League does not need 8 kHz, so weight is the real reason to buy.
- Lowest published weight of the five
- Up to 95 hours at 1,000 Hz
- Symmetrical shell
- DPI switch sits on the underside
- Battery falls sharply at higher polling rates
A good fit if every gram counts.
Razer Viper V3 HyperSpeed
Six programmable buttons and up to 280 hours on one AA battery.
Razer lists the Viper V3 HyperSpeed at 82 g with its AA battery (59 g without) and up to 280 hours of battery. Tom’s Hardware describes its six programmable buttons as left, right, two left-side thumb buttons, a center DPI switch and a clickable wheel.
That is a fourth reachable slot, and the reason it is our support pick: Flash, trinket and a ping can all sit on the mouse. Razer lists second-generation mechanical switches rated for 60 million clicks.
- Four spare slots, the most of the five
- Up to 280 hours on one AA battery
- 59 g without the battery
- 82 g with the battery installed
- Binding the DPI button removes on-mouse DPI switching
The best fit when you want a fourth bind, at a weight cost.
Logitech G305 LIGHTSPEED
99 g, six programmable buttons, up to 250 hours on one AA.
Logitech lists the G305 at 99 g with a HERO sensor up to 12,000 DPI, LIGHTSPEED wireless with a 1 ms response time, and up to 250 hours on one AA. Its copy names six programmable buttons: left, right, middle click, a DPI button and two side buttons.
You keep both thumb buttons on a lower-spec mouse, so Flash and trinket fit as they do on the pricier models. You give up weight (it is the heaviest of the five) and the newest sensor.
- Both thumb buttons plus a DPI button
- Up to 250 hours on one AA battery
- Built-in storage for the nano receiver
- 99 g, the heaviest of the five
- Lower maximum DPI than the other four
Choose it when budget leads.
🔗 Pairs well with: our keyboard and mouse combo guide if you are buying a whole setup
🛒 See Logitech G305 LIGHTSPEED on Amazon →Best for support players
The Razer Viper V3 HyperSpeed is our pick. In our editorial view, supports lean on vision and pings more than most roles, so the trinket and alert ping rank high, with Flash beside them.
It gives you four spare slots: Flash and trinket on the thumb buttons, a ping on the center DPI button. The Logitech G305 has a similar six-button layout, but Logitech’s copy does not say where its DPI button sits, so we cannot confirm it is reachable mid-game. See the full card.
Best budget pick
Choose the Logitech G305 to spend least and still keep the binds that matter. Both side buttons are documented, so Flash and trinket fit as they do on the lightest mice here. The cost is weight: 99 g, against 54 to 63 g for three of the others.
Prices change often, and we have not verified which of the G305 and Viper V3 HyperSpeed is cheaper right now, so compare them on Amazon the day you buy. Building a whole setup? See our keyboard and mouse combo guide. See the full card.
How GameVexo chose
Evidence basis: This guide is research-based. GameVexo did not hands-on test these mice, and nothing here is a GameVexo measurement. Specs are the manufacturers’ published figures, as repeated by retailers.
What came from documentation: Weight, sensor, battery, button counts and switch ratings come from Logitech and Razer specifications. League’s default keys and casting modes come from the League of Legends Wiki.
Independent evidence: Button placement for the Viper V3 HyperSpeed comes from Tom’s Hardware, and the Viper V3 Pro’s underside DPI switch from TweakTown. Those are reviewers’ descriptions, not ours. We did not benchmark latency, accuracy or comfort.
How picks are chosen: In order: buttons reachable mid-game (the binding map), weight, battery, then shape. “Best overall”, “best for support” and “best budget” are editorial judgments from those criteria, not sales rankings. We do not list prices. Product links are Amazon affiliate links.

Buying Guide — What to Look For
Count reachable buttons, not total buttons
Headline counts include left click, right click and sometimes an underside DPI switch. What counts is how many your thumb can press mid-fight.
Read weight and battery together
The Viper V3 HyperSpeed is 82 g with its AA battery and 59 g without. Check which figure a listing quotes.
Check shape and handedness
Thumb buttons usually sit on one side only, even on a symmetrical shell.
Confirm the exact listing
Retailers sell variants, such as 4K and 8K versions of the Superlight 2 and the Viper V3 Pro SE. Make sure the Amazon page matches your model.
Frequently Asked Questions
Final Verdict — Which Should You Buy?
Pick by shape, weight and battery first. All five give you at least two thumb buttons, so the binding map differs by only one slot.
