Zone Poker vs Ring on Ignition: The Measured Differences

Zone Poker is Ignition’s fast-fold format: fold and you are dealt into a new hand at a new table. The usual advice is “it plays like a nittier version of the ring game”. We measured the two formats on the same network over the same weeks, with every seat’s cards visible, and that advice is half right.

Preflop: Zone gives away more, not less

We priced every pool preflop decision against solver charts for both formats (method here). The NL200 Zone pool leaks +2.79 ± 0.53 bb/100 per player preflop; the NL200 ring pool leaks +1.70 ± 0.19. That is the opposite of “nittier”. Our best guess at the cause: in Zone the cost of a bad call is a few seconds, not a seat at a table you might lose, so people call wider. The dominant leak in both formats is cold-calling opens.

Postflop: more stabbing, bigger sizes

When the pool is first to act on the flop:

Zone players bet the flop 5 points more often, and they choose a medium size almost twice as often as ring players, who prefer small. Big bets and overbets are rare in both.

By the turn and river the formats converge: first-to-act check rates are 58% on the turn and 61–62% on the river in both.

Facing a bet: Zone folds a little more

Read this chart with the sample sizes. Zone’s 57% fold to a medium flop bet against ring’s 50% is the biggest gap, but the ring cell has 38 decisions. The honest summary is that the pool folds to a medium bet about half the time on the flop and turn and about 60% on the river, in both formats, and small bets get called about 60% of the time everywhere. The pool also raises more than you might expect against small bets: 10–14% raise rates, nearly all of them large.

No reads, by construction

On a ring table a player with the hand history can follow a seat from hand to hand with 98.6% precision (we measured this: how anonymous are Ignition tables). In Zone, re-seating every hand breaks the chain: 33,449 seat-observations resolved to 21,270 ids, 1.57 hands each. Every Zone opponent is the population average, and the only adjustments available are the ones the data above supports.

That cuts both ways. Your own play is unreadable too, which makes Zone the format where a fixed, well-built strategy gives up the least.

Which should you play?

• Zone if you want volume against a pool that leaks more preflop and can never adjust to you. The price is that you cannot adjust to them either beyond population tendencies.
• Ring if you can use within-table information, or if you want the softer tables that a lobby lets you choose. Expect fewer hands per hour and a slightly tighter preflop pool.

For a strategy that already plays against a pool model rather than reads, Zone’s higher preflop leak is a straightforward edge. Our own NL200 Zone sample is small (827 hands, +29 ± 35 bb/100 luck-adjusted), so we will update this when it is not.
