GTO Wizard Rolls Out Custom Multiway Preflop Solving

What the Multiway Preflop Upgrade Means

The headline reads like this: players now have the ability to solve custom multiway preflop spots instead of relying on fixed charts. In rookie-friendly terms, this means you, as a player, now have the ability to adjust key variables and see optimal strategy (potentially) change with them.

It can be boiled down into four points:

• Multiway preflop solving available for up to nine players: Supports full-ring, short-handed, and heads-up configurations within the same system.
• Fully customizable table conditions: Players can set exact stack sizes, rake structures, antes, straddles, open sizes, limps, and blind actions.
• Nodelocking and player profiles: Specific ranges or behaviors can be locked in to reflect loose opens, passive callers, or aggressive 3-bettors.
• Fast, browser-based solving: Solutions run in seconds and work on desktop and mobile, without the need for local computing power.

The biggest change is going to be seen in moving away from equating preflop charts to universal answers. A standard preflop chart usually works off clean conditions, which means uniform stacks, small opens, low rake, and predictable responses. Once any of those change (and they usually will), the chart’s starts to wobble.

if you have something like a multiway preflop solver, you can model a live cash game where a cutoff opens to five big blinds, stacks are uneven, and rake is high. When you apply those inputs, the resulting strategy can look very different from what preflop charts would suggest.

Access, Tiers, and the Ultra Plan

GTO Wizard isn’t interested in gatekeeping this upgrade. It made the updated preflop engine immediately available in study mode, where players are able to test multiway preflop spots using short stack configurations.

Full multiway preflop solving is being placed under a new Ultra tier. According to GTO Wizard, multiway solving places significantly higher demands on infrastructure, and the new tier is intended to keep solve times fast and reliable as is usage inevitably grows.

The Ultra tier includes unlimited multiway preflop solving, expanded multiway postflop solving, monthly solver credits for aggregated reports, and access to an exclusive discussion channel. Additional features, such as ICM-aware preflop solving and bounty tournament support, are planned and promised for future updates.

What We Think of the Upgrade

For years now, studying preflop meant finding shortcuts, especially once more than two players enter the pot. Multiway preflop has given solvers headaches because complexity rises with each additional player. Every extra seat increases the number of ranges, actions, and outcomes the solver has to consider.

The new engine is designed to accept those messy inputs. Instead of asking whether a chart is “close enough,” players can now model the game and see how optimal strategy responds. For anyone trying to understand preflop play beyond textbook scenarios, this is step forward we’ve all been waiting for.
