Counted from Ranked matches of top players over the last 21 days, last updated 2026-09-29. Matches played before the latest balance change count for less.

Players take Grom into Knockout most often: 51% of its matches are played there, where it wins 52% (111 matches, fairly reliable). Grom wins clearly more often than it loses in Knockout: 52% over 111 matches (fairly reliable), 10 points above its overall win rate. Grom loses far more often than it wins in Bounty: 37% over 59 matches (early signal), 5 points below its overall win rate. Too few matches to show a win rate: Brawl Ball (23 matches), Hot Zone (19 matches), Gem Grab (4 matches), Heist (3 matches).

Grom's strongest measured map is Belle's Rock (Knockout): 59% over 41 matches (early signal). 2 maps have at least 30 Grom matches; maps with fewer are left out.

A win rate only means something when enough matches sit behind it. Next to every number we say how sure we are:

• reliable — 200 matches or more: a solid basis for a verdict.
• fairly reliable — 80 to 199 matches: enough to spot a real pattern.
• early signal — 30 to 79 matches: a hint, not a verdict.
• too few matches — fewer than 30 matches, so we do not show a win rate yet.

A 60% win rate over 40 matches can easily be luck; a 54% win rate over 800 matches is a real edge. Maps and modes with fewer than 30 matches are listed without a win rate on purpose.

Blind-pick safety is coaching metadata, not a meta ranking: it says how risky Grom is to lock in before you can see the enemy draft. Grom scores 6/10.

Gadget: Watchtower — Vision of the map so you hit accurately behind walls without seeing.

Star Power: X-Factor — Extra damage at the impact point rewards precision on fixed lanes.

Gears: Gadget Charge + Shield — You have no escape and need to survive one dive.

Stand behind a wall and spam the only passage.

As a thrower, Grom is favoured into tank, controller, fighter.

• With your cross explosion behind walls you focus Bo: controllers have low burst and go down fast under focus.
• With your cross explosion behind walls you focus Lou: controllers have low burst and go down fast under focus.
• With your cross explosion behind walls you focus Shelly: fighters lose once you keep them outside their effective range.
• With your cross explosion behind walls you focus Jessie: Jessie relies on her turret and is weak herself.

Grom struggles against assassin, marksman, sharpshooter and on maps that do not support the thrower role.

This is the coaches' view of which modes suit the thrower role of Grom; the measured win rates per mode are higher up on this page.

• Gem Grab — fit 6/10
• Knockout — fit 6/10
• Hot Zone — fit 6/10

Grom is a reasonable middle pick — check which counters are still open before locking it.

Learn the pick-order logic in the drafting guide.

Skip Grom when the map layout works against the thrower role, when an unfavourable matchup is still open on the enemy side, or when your team already has the same role covered.
