Tap AI Hint and the online solver scores every legal move with expectimax search — it looks several moves ahead, averaging over the random tile spawns — guided by a heuristic that rewards empty space and a clean corner-snake ordering. It then names the strongest direction and why.
AI Auto-Play turns this into a 2048 auto solver: hand the whole board to the engine and watch this game solver solve 2048 automatically, move by move, right in your browser. Toggle auto play off any time to take over.
How well does the 2048 solver actually play? On the classic 4×4 board, we ran its exact search code headless for 250 self-play games (standard 90% “2” / 10% “4” spawns) and measured how far it gets:
92.8% reach the 2048 tile — a win (232 / 250 games)
64.0% push on to 4096 (160 / 250)
10.8% break through to 8192 (27 / 250) — the solver’s current ceiling
Those figures are for the standard 4×4 board — see the FAQ below for how the AI does on this 5×5 board.
Yes — 5x5 2048 is easier than 4x4. 25 cells give you far more breathing room than 16, so runs last longer and bigger tiles are reachable. In our 100-game self-play test the AI reached 2048 in 98% of runs on 5x5, against roughly 93% on the classic board.
What's the highest tile possible on a 5x5 board?
The theoretical ceiling is 2²⁶ = 67,108,864 — a limit set by the 25 cells plus the fact that spawns can be 4s. No human or program gets anywhere near it; in practice 5x5 is about chasing 4096, 8192 and beyond. In self-play testing here, the solver reaches 16,384 in over half of games and 32,768 in about a quarter, so tiles in that range are the realistic target rather than the theoretical max.
Do the AI hint and autoplay work on 5x5?
Yes — the same expectimax search that powers the classic 4x4 solver runs here, recalculated for the 5x5 grid. Hints suggest one move; autoplay plays the whole board for you. Use the speed slider to set how fast autoplay moves, and toggle it off anytime to take back manual control.
Does the corner-snake strategy still work on 5x5?
Yes — pin your largest tile in one corner and build a descending chain of values along each row, exactly like the classic 4×4 strategy. The extra row and column give you more slack before you're forced to break the pattern, which is part of why the solver's win rate is higher here than on 4×4. Stick to three directions and avoid moving away from your anchor corner.
The 5×5 board sits between the classic 4×4 and the roomier 6×6 — enough extra space to chase far bigger tiles. Here is the median score our AI is sitting on the moment each tile first appears, from a 40-game self-play run on this 5×5 board:

Median cumulative score when each tile first appears, across a 40-game self-play run of the LK Forge solver on the 5×5 board. Unlike the bigger boards, 5×5 games do eventually jam, so the higher tiles are reached less often. For the classic-board figures, see the 2048 score ladder.
